Just look at q4 i need this question

A=78.23in²

Step-by-step explanation:

First we need to solve for the radius. The volume of a cylinder can be found using the formula:

Now we have the variables:

V = 1177.5 in³

h = 15

r = ?

≅24.99

≅

r≅4.99in

Now since we're looking for the area of the base, we can use the formula for the area of a circle which is:

A=78.23in²

you answer is a

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
