Answer

16

Explanation

Functions are:

g(x) = 2x and h(x) = x2 + 4

To evaluate g(-2) substitute x = -2 into the function.

2 • -2 = -4

To evaluate h(4) substitute x = 4 into the function.

4^2 + 4 = 20

Add the 2 functions

-4 + 20 = 16

The surface are of the right cone is 176 sq.units. Option A) is the correct answer.

Step-by-step explanation:

step 1 :

Radius of the cone, r = 4

Height or length of the cone, h = 10

step 2 :

Total surface area of right cone = πrh + πr^2

= (π $\times$ 4 $\times$ 10) + ( π $\times$ 4^2)

= 40π + 16π

= 56 π = 56 $\times$ 3.14

= 176 sq.units
