Step-by-step explanation:
Answer:
3x
Step-by-step explanation:
The area of a triangle is (base × height)/2.
In this picture, the base is 3.
The height is 2x.
(3×2x)/2
=6x/2
=3x
.
<u>Find Radius:</u>
Radius = Diameter ÷ 2
Radius = 4 ÷ 2 = <u>2 in</u>
.
<u>Find Surface Area:</u>
Surface Area = 2πr² + 2πrh
Surface Area = 2π(2)² + 2π(2)(3)
Surface Area = 8π + 12π
Surface Area = 2<u>0π in²</u>
.
Answer: 20π in²
