Step-by-step explanation:
Surface area is the sum of areas of 4 triangles.
<u>Each triangle has:</u>
<u>Area of each triangle:</u>
- A = 1/2bh
- A = 1/2*9*7.79 = 35.055 ft²
<u>Surface area:</u>
- S = 4*35.055 = 140.22 ft²
Answer:
3051.08 cm squared
Step-by-step explanation:
The equation to find lateral surface area of a cone:
SA = pi r sqrt(h^2 * r^2)
Plug your values in.
SA = 3.14 * 9 * sqrt(144*81)
SA = 3.14 * 9 * 108
SA = 3051.08
The lateral surface area is 3051.08 cm squared.
Try 126 divided by 7. Then, do 128 minus the answer to 126 divided by 7.
