A painter needs to paint the bottom of a circular pool. The pool has a radius of 30 feet. A store sells 5-gallon cans of paint.

oksano4ka [1.4K]

Answer:

2 cans

Step-by-step explanation:

Given that :

Radius of pool = 30 feets

Using the relation for the Area of a circle :

Area = pi*r^2

Thus,

Area of pool = 3.14 * 30^2

Area of pool = 3.14 * 900 = 2826feet²

Paints are sold in cans of 5 gallon

5 gallon of paint = 1500 feet²

Least number of 5 gallon can required :

2826 feet² / 1500 feet² = 1.884 cans

Hence,

Least number of 5 gallon can required = 2 cans

- 26 = 8 + 5(a + 2)

yawa3891 [41]

Answer:

-44/5 = a

Step-by-step explanation:

- 26 = 8 + 5(a + 2)

Subtract 8 from each side

- 26-8 = 8-8 + 5(a + 2)

-34 = 5(a +2)

Distribute

-34 = 5a +10

Subtract 10 from each side

-34-10 = 5a +10-10

-44 = 5a

Doivide each side by 5

-44/5 = 5a/5

-44/5 = a
