Question

Find the surface area of the cylinder. Round your answer to the nearest tenth.

Answer 1

4245.3cm

Explanation:

Answer 2

4247.4 (1 d.p.)

Explanation:

• The formula for the surface area of a cylinder is
  `A=2\pi rh+2\pi r^(2)`, where A is the surface area, r is the radius, and h is the height
• Put in the values
• 
  `A=2\pi* 13* 39+2\pi* 13^(2)`
• 
  `A=1014\pi +338\pi`
• 
  `A=1352\pi=4247.4`
