8x * 7x = 56x^2 = whole yard
𝜋 (3x)^2 = 𝜋 9 x^2 = pool
left over yard = whole yard - pool = 56x^2 - 9𝜋 x^2
A family is having a pool built in their backyard. If their backyard is rectangular and measures 8x by 7x and the pool is circular with a radius of 3x how much of the yard will be left over after the pool is built?
a. 56𝑥^2−9𝜋𝑥^2
b. 65𝑥^2
c. 56𝑥^2−3𝜋𝑥^2
d. 65𝜋𝑥^2
