Question

Use the formula V= πr²h, where π ≈ 22/7 to estimate V when r = 3 feet and h = 10 ​

Answer 1

Use the formula V= πr²h

π =
`(22)/(7)`

r = 3 ft

h = 10 ft

^^^^Plug these numbers into their corresponding spot into the formula given above

V =
`(22)/(7)`×
`3^(2)`×10

To evaluate apply the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

Parentheses

There are none so go on to the next step

Exponent

`3^(2)` = 9

so...

V =
`(22)/(7)`×9×10

Multiplication (multiply from left to right)

V =
`(198)/(7)`×10

V =
`(1980)/(7)`

V ≈ 282.857 ft³

Hope this helped!
