Answer:
283 cm^2
Step-by-step explanation:
Solution:-
We have a cone with a circular base of radius r = 5 cm
The height of the cone is h = 12 cm
The slant height of the cone is L = 13 cm
We are to determine the surface area of the cone. The surface area of the cone is comprised of two parts:
Base Area : Circle

Curved Surface: conical

The total surface area of the cone can be written as ( A ):

Answer: The surface area of the cone to nearest whole number would be 283 cm^2
Answer:
m= 1/3
Step-by-step explanation:
3/99 = 1/33
So 3 ÷ 99 = 1/33 = 0.030303030303, or 33%
Answer:
A (4x-12)
Step-by-step explanation:
Still think of PEMDAS: 8-4(-x=5)
a) Multiply -4(-x + 5)
* -4(-x) = 4x (remember a neg x neg = pos)
* -4(5) = - 20
b) Now it reads = 8 +4x - 20
c) put all like terms together
* 8 - 20 = -12
