A company rents water tanks shaped like cylinders. Each tank has a radius of 3 feet and a height of 2 feet. The cost is $4 per c

Tatiana [17]

Answer:

$\$226.08$

Step-by-step explanation:

step 1

Find the volume of the tank (cylinder)

The volume of cylinder is given by the formula

$V=\pi r^{2}h$

we have

$r=3\ ft\\h=2\ ft\\\pi=3.14$

substitute

$V=(3.14)(3)^{2}(2)$

$V=56.52\ ft^3$

step 2

Find the cost of rent one tank

Multiply the volume of one tank by the unit rate of $4 per cubic foot

$56.52(4)=\$226.08$

Anna buys a sweater for $25.60, and it is on sale for 35% off. What is the amount of the discount?

inysia [295]

To find the answer of this question, you have to multiply 25.60*0.35, since 35% equals 0.35 and the original price of the sweater was 25.60. After you do this, you should get $8.96 as the amount of the discount.
