Answer:

x = 15

Step-by-step explanation:

The 2 angles are corresponding angles and they are always equal to each other.

5x + 55 = 2x + 100

Subtract 2x from each other;

3x + 55 = 100

Subtract 55 from both sides;

3x = 45

Divide both sides by 3;

x = 15

<em>Check:</em>

5x + 55

Substitute x;

5(15) + 55 = 75 + 55 = 130

2x + 100

Substitute x;

2(15) + 100 = 30 + 100 = 130

the lateral area of a cylinder is 325 pi in2 the radius is 13 in find the following Volume. surface area 
Nesterboy [21]
Volume: 2112.5π
Surface Area: 663π

First, let's find the height of the cylinder. Using the formula for lateral surface area, 2*π*r*h:

2*π*13*h = 325π
(divide π by both sides)
26h = 325
h = 12.5 in.

Next, let's solve the surface area of the cylinder using the formula π*r²*h.

π * 13² * 12.5 = π * 169 * 12.5 = 2112.5π.

Next, let's solve the surface area using the formula 2πrh + 2πr².
 
(2 * π * 13 * 12.5) + (2 * π * 13²) = 325π + 338π = 663π.
