Circle Calculator ek circle ki chaar main measurements — radius, diameter, circumference aur area — kisi bhi ek pehle se maloom value se nikal deta hai. Choose karein ki aap radius, diameter, circumference ya area daal rahe hain, number type karein, aur baaki teen values standard formulas se turant update ho jaati hain: diameter = 2 × radius, circumference = 2 × π × radius, aur area = π × radius². Yeh geometry homework, kisi round table ya pipe ka size nikalne, round garden bed ke liye material estimate karne, ya kisi CAD measurement ko double-check karne ke liye kaam aata hai. Har result poori floating-point precision ke saath calculate hota hai aur readability ke liye rounded dikhaya jaata hai. Sab kuch aapke browser mein type karte hi locally chalta hai, kuch bhi upload nahi hota.
Features
Kisi bhi ek maloom value se radius, diameter, circumference ya area solve karein
Ek click mein maloom field badlein aur layout apne aap adjust ho jaata hai
Standard circle formulas use karta hai: diameter = 2r, circumference = 2πr, area = πr²
Type karte hi turant sab chaar results update hote hain — calculate button ki zarurat nahi
Radius, diameter, circumference aur area ka plain-text summary ek click mein copy karein
Value zero, negative ya missing hone par clear error message
Input mein thousands separators aur extra whitespace accept karta hai
Poori tarah aapke browser mein chalta hai, kuch bhi upload nahi hota
Circle Calculator kaise use karein
Choose karein aap kaunsi value jaante hain: radius, diameter, circumference ya area
Us number ko input field mein type karein
Neeche turant calculate hui baaki teen measurements dekhein
Copy button se poora result summary copy karein
Example
Input
r=5
Output
C=31.42, A=78.54
5 radius se circumference 2 × π × 5 ≈ 31.42 aur area π × 5² ≈ 78.54 milta hai.
Common errors aur troubleshooting
Circle Calculator result ki jagah error dikha raha hai. — Maloom field mein zero se bada positive number daalein — blank, zero ya negative value se baaki measurements nikalna possible nahi.
Circle ka area calculator expected se kaafi bada number de raha hai. — Area radius ke square ke saath badhta hai, isliye radius double karne se area 4 guna ho jaata hai — yeh expected behavior hai, bug nahi.
Radius se diameter switch karne par result unexpectedly badal jaata hai. — Newly selected field ke liye value dobara enter karein — 5 radius, 5 diameter jaisa nahi hota, isliye input ko wahi match karna chahiye jo aap ab solve kar rahe hain.
Circumference calculator ka result hand calculation se match nahi ho raha. — Check karein ki aapne π ke kaafi digits use kiye (tool full double precision use karta hai) aur aap circumference compare kar rahe hain, diameter ya area nahi.
Aksar pooche jaane wale sawaal
Circle Calculator kya-kya solve kar sakta hai?
Radius, diameter, circumference ya area mein se koi bhi ek daalein, aur Circle Calculator standard circle formulas se baaki teen apne aap nikal deta hai.
Kya Circle Calculator area ya circumference se radius nikaal sakta hai?
Yeh area = π × radius² apply karta hai. Agar aap radius ki jagah diameter, circumference ya area daalte hain, to Circle Calculator pehle radius nikalta hai, phir usse area calculate karta hai.
Circumference calculator kaunsa formula use karta hai?
Circumference = 2 × π × radius, jo π × diameter ke barabar hai. Koi bhi maloom value daalein aur Circle Calculator pehle radius, phir circumference calculate karta hai.
Kya main radius ki jagah diameter daal sakta hoon?
Haan. Known-value selector ko Diameter par switch karein, diameter daalein, aur radius calculator circumference aur area nikalne se pehle usse do se divide kar deta hai.
Kya Circle Calculator kisi bhi measurement unit ke saath kaam karta hai?
Haan, yeh unit-agnostic hai. Kisi bhi consistent unit (inches, meters, etc.) mein radius, diameter ya circumference daalein, aur area us unit ke square mein milega.
Kya Circle Calculator mere numbers upload karta hai?
Nahi. Saare calculations aapke browser mein locally chalte hain. Aapke type kiye values kabhi aapke device se bahar nahi jaate aur kuch bhi ArrayKit ke servers ko nahi bheja jaata.
