Question

what is the difference in the areas of a circle with radius 14 ft and a circle wit radius 10 ft? round your answer to the nearest square meter. a) 75 ft^2 b) 160 ft^2 c) 302 ft^2 d) 537 ft^2

Answer 1

A = pi * r^2

radius 14 ft
A = 3.14 * 14^2
A = 3.14 * 196
A = 615.44...rounds to 615

radius 10 ft
A = 3.14 * 10^2
A = 3.14 * 100
A = 314

difference is : 615 - 314 = 301...I guess it is C...because of the rounding
