<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 =
=
1084 in²

<u>Answer:</u>
- The length of the hypotenuse is 36 miles.
<u>Step-by-step explanation:</u>
<em>We can solve for 'a' using Pythagoras theorem. Let's solve it.</em>
- 39² = a² + 15²
- => 1521 = a² + 225
- => a² = 1296
- => a = 36
Hence, the length of the hypotenuse is 36 miles.
Hoped this helped.
