A cylinder has a height that is twice the length of the diameter. The diameter of the cylinder is 10 centimeters. What is the su
siniylev [52]

Answer:

Step-by-step explanation:

Givens

pi = 3.14

d = 10 cm

h = 2*d

Formula

  • The top of the cylinder is a solid circle. So the area of the circle is pi r^2
  • There is both a top and bottom to the circle so the fomula is 2*pi*r^2

  • The surrounding area of the cylinder is the circumference of the circle times the height. The circumference of the circle is 2*pi*r.
  • Then you just multiply by the height.
  • formula = 2*pi * r * h

The combined formula is given below.

SA = 2*pi*r^2  +  2*pi*r * h

Conversions

d = 10 cm

h = 2*10

h = 20 cm

r = d/2

r = 10 / 2

r = 5cm

Solution

SA = 2*pi*r^2  +  2*pi*r * h

SA = 2*3.14*5^2 + 2*3.14*5*20

SA = 157 + 628

SA = 785 cm^2

Answer: The surface area is 785 cm^2
