Answer:
Step-by-step explanation:
Given that,
The diameter of the base of a circular cone, d = 18 inches
Height of the cone, h = 40 inches
We need to find the lateral surface area of the cone. The formula of the lateral surface of the cone is given by :
l is the slant height of the cone,
, d = 18 inches, r = 9 inches
So,
So, the lateral surface area of the cone is 
.
Answer:
Step-by-step explanation:
SA=1/2(Perimeter of Base)(slant height) + Area of Base
SA=1/2(14X4)(25) + (14X14)
SA=1/2(56)(25) + (196)
SA=1/2(1,400) + 196
SA=700+196
SA=896 square meters
I need to see the work sheet tho! I’ll help you
When you add integers, you keep the sign on the sum.
For example:
-9 + -9 = -18 (kept the sign)
9 + 9 = 18 (kept the "sign")
