Answer 1

Answer: $1267.18yd^2$

Step-by-step explanation:

$Formula: \pi r(r+\sqrt{h^2+r^2} )$

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.

$\frac{d}{2}= \frac{24}{2}=12yd$

Now plug this info into the formula.

$(3.14)(12yd)[(12yd)+\sqrt{(18yd)^2+(12yd)^2} ]$

Let's solve the square root first.

$(3.14)(12yd)[(12yd)+\sqrt{324yd^2+144yd^2} ]$

$(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]$

$(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]\\(3.14)(12yd)(12yd+21.63yd)$

Now solve the sum

$(3.14)(12yd)(33.63yd)$

Multiply

$1267.18yd^2$
