Question

Find area of circle given radius of (3x^9 y^11)

Answer 1

Formula for area:
`\pi {r}^(2)`

Area of circle:

`(\pi3 {x}^(9) {y}^(11) {)}^(2)`

`\pi {3}^(2) {x}^(9){ * }^(2) {y}^(11) { * }^(2)`

`9\pi {x}^(18) {y}^(22)`

Answer 2

Given radius:
`3x^9 y^(11)`

Formula for area: πr²

Area of circle:

(
`\pi 3x^9 y^(11)` )²

`\pi 3^2x^(9*2 )y^(11*2)`

`9\pi x^(18)y^(22)`

Answer:
`9\pi x^(18)y^(22)`
