<u>Answer:</u>
Surface area = 1084 in²
<u>Step-by-step explanation:</u>
To find the surface area of a right cone, we can use the following formula:
,
where:
• r = radius
• l = slant height.
In the question, we are told that the diameter of the cone is 30 in. Therefore its radius is (30 ÷ 2 = ) 15 in. We are also told that its height is 8 in.
Using this information and the formula above, we can calculate the surface area of the cone:
Surface area = ![\pi \times (15)^2 + \pi \times 15 \times 8](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%2815%29%5E2%20%2B%20%5Cpi%20%5Ctimes%2015%20%5Ctimes%208)
= ![345 \pi](https://tex.z-dn.net/?f=345%20%5Cpi)
1084 in²
