Area of a circle in square cm = pi*radius squared
16.328 cm squared.
56 cm squared
630 cm squared equals 97.65 inches square.
60cm
Since area equals Pi times radius squared take and substitute what is known. 345 equals Pi times the radius squared. divide Pi into both sides for 109.8 equals the radius squared. Now take the square root of 109.8 to get an r of 10.47936 cm.
Area of a circle in square cm = pi*radius squared
1.63 cm
Well, darling, to find the area of a circle, you use the formula A = πr^2. So, plug in that radius of 4.4cm and you get A = π(4.4)^2. Crunch the numbers and you'll find the area is approximately 60.82 square centimeters. Voila!
The answer is 254.469005cm squared
16.328 cm squared.
56 cm squared
9474.76 cm squared 3730.22 in squared
if a radius is 5cm the diameter is 10cm rule- you double the radius
630 cm squared equals 97.65 inches square.
60cm
The circumference = 18.8 cm
