Total surface area of a cone is given by,
Surface area of the cone = πrl + B
Here, l = Slant height of the cone
r = radius of the circular base
B = Area of the base
From the picture attached,
Slant height 'l' = 15 in.
Radius of the circular base 'r' = 12 in.
Area of the circular base = πr²
= π(12)²
= 144π in²
By substituting these values in the expression of the surface are,
Total surface area of the cone = π(12)(15) + 144π
= 180π + 144π
= 324π in²

The equation of a circle uses the following formula:
The center of the circle is given by (h,k). Therefore, h = -2, and k = -5. r = 1, so we can find the equation from the information given to us.
Plug in your values.
The equation of this circle is as follows:
Answer:
FH = 108
Step-by-step explanation:
The given figure requires we use the Pythagorean theorem to write two relations involving right triangle side lengths. The Pythagorean theorem tells us the square of the hypotenuse is the sum of the squares of the other two sides.

<h3>Triangle EGH:</h3>
EG² = GH² +HE²
GH² = EG² -HE² = 53² -28² = 2025 . . . . . solve for GH², use given values
<h3>Triangle FGH:</h3>
FG² = GH² +FH²
FH² = FG² -GH² = 117² -2025 = 11664 . . . . solve for FH², use known values
FH = √11664 = 108 . . . . . take the square root
The length FH is 108.
