Question

You need to buy a cover for your circular pool. If your pool has a radius

of 2 m, about how large should the cover be?

Answer 1

Answer: A=12.56 m²

Explanation:

Given:

r=2

Reasoning:

To cover a pool you need area. How large is the pool area.

Solution:

Formula for Area for a circle

A=
`\pi r^(2)` substitute r=2

A=
`\pi (2^(2) )` use 3.14 for pi

A=3.14(2²) 2²=4

A=3.14(4) multiply

A=12.56 m²

Answer 2

The cover should be at least 4 meters in diameter to cover the entire circular pool.

Explanation:

To determine the size of the cover, we need to calculate the diameter of the pool, which is twice the radius.

Diameter = 2 x radius = 2 x 2 m = 4 m
