C. 28.26 cm 2
How do you calculate the diameter of a circle?
Diameter = 2 * Radius (r) Area of the circle radius. The radius of the circle calculator uses the following area of the circle formula, Area of a circle = π * r 2
What is the area of a circle with diameter 6 centimeters?
Area = π· ( d2) 2 = 3.14· ( 62) 2 = 3.14· (3) 2 = 28.27 square centimeters (*) Area = C2 4π = 18.852 4π = 355.32(4·3.14) = 355.3212.56 = 28.27 square centimeters (*)
The first formula is A=πr², or the second formula is d=2r. Now, we could solve for a,
A=1/4πd²=1/4*π*6²=28.27433cm²,
Therefore, the solution is 28.26 cm 2
