Question

James is putting a brick border around his circlar Pool. The bricks are 1 foot in length. How many brick does need to buy to build the border. Use 3.14 for π

Answer 1

Explanation:

Using the formuka for calculating equation of a circumference

C = 2πr

r is the radius

Given

r = 1foot

C = 2π{1)

C = 2(3.14)

C = 6.28foot

Hence he needs about 6 bricks to build the border
