Given:
In the given cone,
Radius of the cone = 7.2 m
Slant height of the cone = 17 m
To find:
The surface area of the cone.
Solution:
The surface area of a cone is:

Where, r is the radius of the cone and l is the slant height of the cone.
Putting
in the above formula, we get




Therefore, the surface area of the given cone is 547.11 square m.

Answer:
A
Step-by-step explanation:
Given
p² - 16 = 0 ( add 16 to both sides )
p² = 16 ( take the square root of both sides )
p = ±
= ± 4
Thus solution is { - 4, 4 } → A
