Answer: x=25
(2x + 15) + x = 90º
3x + 15 = 90
3x = 75
x = 25
Answer:
Step-by-step explanation:
C is the answer to the problem
The surface area of the right cone with a radius of 3 meters and a slant height of 5 meters is 47.1 m².
What is surface area?
To calculate the surface area of the cone, we use the formula below.
Formula:
- A = πrl.............. Equation 1
Where:
- A = Surface area of the cone
- π = Pie
- l = Slight Height
From the question,
Given:
- l = 5 meters
- r = 3 meters
- π = 3.14
Substitute these values into equation 1
Hence, The surface area of the right cone is 47.1 m².
