The radius of a cylinder is 5 inches and the height of the cylinder is 15 inches. Find the area of the cylinder. (Take the value of pi as 3.14)
What is 628 in2?
Radius, r = 5 in
Height of the cylinder, h = 15 in
The surface area of cylinder is: =2πr2 +2πrh or
= 2πr(r+h)
= 2π × 5 × (5 + 15)
= 2π × 5 × 20
= 2 × 3.14 × 5 × 20
= 628

Samuel has a cylinder with a total surface area of 1728π square units. Find the height of the cylinder if the radius of the base of the circle is 24 units.
What is 12 un2?
The total surface area of the cylinder, A = 1728π; radius (r) = 24; h = ?
Let us substitute the given values in the formula to find the height of the cylinder.
SA = 2πr2 + 2πrh
1728π = 2π24^2 + 2π24h (Do not calculate π)
⇒ 1728π = 1152π + 48πh (divide all terms by 48π)
⇒ 1728π/48π = 1152π/48π +48πh/48π
⇒ 36 = 24 + h (subtract 24 from each side)
⇒ h = 12
