Answer 1

Answer:
`1267.18yd^2`

Explanation:

`Formula: \pi r(r+√(h^2+r^2) )`

We need;

`\pi = 3.14\\r=?\\h=18yd`

We don't have the radius, but we do have the diameter. A diameter is twice the radius. Therefore, we can divide the diameter by 2 in order to obtain the radius.

`(d)/(2)= (24)/(2)=12yd`

Now plug this info into the formula.

`(3.14)(12yd)[(12yd)+√((18yd)^2+(12yd)^2) ]`

Let's solve the square root first.

`(3.14)(12yd)[(12yd)+√(324yd^2+144yd^2) ]`

`(3.14)(12yd)[(12yd)+√(468yd^2) ]`

`(3.14)(12yd)[(12yd)+√(468yd^2) ]\\(3.14)(12yd)(12yd+21.63yd)`

Now solve the sum

`(3.14)(12yd)(33.63yd)\\`

Multiply

`1267.18yd^2`
