Step-by-step explanation:

The question is basically asking you how much area of the yard the pool takes up, in essence the area the pool takes up.
So we are going to find the area of the pool.
Area of pool is = pi x r^
= 3.14 x 7^2
= 153.86 ft^2
Therefore the pool takes up 153.86 ft^2 of space.
1 b
2 f's
2 j's
3 e's
4 d's
5 n's
7 c's
8 h's
A =

bh Multiply both sides by 2 to cancel out the fraction
2A = bh Divide both sides by b

= h Switch the sides to make it easier to read
