radius = 3 feet
rearrange the formula making r the subject
πr³ = V ( multiply both sides by 3 to eliminate fraction )
4πr³ = 3V ( divide both sides by 4π )
r³ = 
= ( 3 × 36π ) / 4π = 3 × 9 = 27
take the cube root of both sides
r = ![\sqrt[3]{27}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%7D)
= 3
115:2 should be the correct answer in reduced form.
Factor the following:
12 x^2 y - 32 x y + 8 y
Hint: | Factor common terms out of 12 x^2 y - 32 x y + 8 y.
Factor 4 y out of 12 x^2 y - 32 x y + 8 y:
Answer: 4 y (3 x^2 - 8 x + 2)
<span>The question is asking us to determine the length of the floor of a rectangular deck. The rectangular deck has an area of 600 squared feet. The floor is 20 feet wide ( W = 20 ft ). Formula for the area of the rectangle is: A = L x W. 600 = L X 20; L = 600 : 20; L = 30 ft. Answer: The floor is 30 ft long.</span>
