Answer:

  138.16 in²

Step-by-step explanation:

The surface area SA of the cone is the sum of the base area B and the lateral area LA. The lateral area is half the product of the circumference and the slant height. The radius is half the diameter, so is 4 inches.

  SA = B + LA

  = πr² + (1/2)(2πrh) . . . . where h is the slant height

  = (πr)(r +h)

Filling in the numbers, you have ...

  SA = (3.14)(4 in)(4 in + 7 in) = 3.14×(44 in²) = 138.16 in²

F - g(2) = 3x^2 + 1 - ( 1 - x )
= 3x^2 + 1 - 1 + x
= 3x^2 + x
= 3(2)^2 + 2
= 14

the answer is B.14

Please help, I will give brainliest, I am struggling badly.
Valentin [98]

Answer:

C

Step-by-step explanation:

A line with a slope of 1/3 using the y=mx+b line slope equation would be:

y=1/3x+b

We can now plug the x and y values into this equation with x being -6 and y being 2.

2=1/3 * -6 +b

2= -2 +b

b=4

Therefore the equation is

y=1/3x+4

C
