A circular lawn has a row of bricks around the edge. The diameter of the lawn is about 40 feet. 1. Which is the best estimate for the total length of bricks.

Length of bricks = 125.6 ft

Step-by-step explanation:

We are given diameter; d = 40 ft

The length of the bricks will be equivalent to the circumference of the circle since the bricks form a row around the edge of the circle.

Circumference of a circle is given by;

C = πd

C = π × 40

C = 3.14 × 40

C = 125.6 ft

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

r = 78539458390583095803458309458039485093485 or just 3
