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
