Question

Estimate the area of the circle. Use 3.14 or 22/7 for π.
explain pls and Thank you

Answer 1

Answer: 616 cm^2

Step-by-Step Explanation:

Diameter = 28 cm
Radius (r) = 28/2 = 14 cm
Area = πr^2

Therefore,
= πr^2
= π * r^2
= 22/7 * 14 * 14
= 22 * 2 * 14
= 616

Area = 616 cm^2

Answer 2

And with the pi of 3.14 you would get 615.44

Because a=pi r^2 a=3.14 14^2 14 squared equals 196 and 196×3.14 equals 615.44
