Answer:
3/4
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.
The rules of exponents allow you to simplify expressions involving exponents. When multiplying two quantities with the same base, add exponents: xm⋅xn=xm+n x m ⋅ x n = x m + n . When dividing two quantities with the same base, subtract exponents: xmxn=xm−n x m x n = x m − n .
X^2 + 12^2 = 13^2
x^2 + 144 = 169
x^2 = 169-144
x^2 = 25
x = sqrt(25)
x = 5
