Answer 1

13.
`36a^2b^4`π

14.
`16x^3y^4`π

15.
`-(c^3)/(4a^7b^3)`

Explanation:

13.

A = π *
`r^2`

r =
`6ab^2`

A = π*
`(6ab^2)^2`

A = π *
`(6ab^2)(6ab^2)`

A = π *
`36a^2b^4`

A =
`36a^2b^4`π

14.

V = π *
`r^2` * h

r =
`2x`

h =
`4xy^4`

V = π *
`(2x)^2` *
`4xy^4`

V = π *
`4x^2` *
`4xy^4`

V = π *
`16x^3y^4`

V =
`16x^3y^4`π

15.
`(3a^(-4)b^2)/(-12a^3b^5c^(-3))` =
`-(c^3)/(4a^7b^3)`

`(3a^(-4)b^2)/(-12a^3b^5c^(-3))`

`(a^(-4))/(-4a^3b^5c^(-3))`

`(b^2)/(-4^(3+4)b^5c^(-3))`

`(b^2)/(-4^7b^5c^(-3))`

`(1)/(-4a^7b^(5-2)c^(-3))`

`(1)/(-4a^7b^3c^(-3))`

`(c^3)/(-4a^7b^3)`

`-(c^3)/(4a^7b^3)`

Hope this helps!
