Below are sample questions representative of the exercises included on this worksheet and related 8.145 Surface Area of Cylinders skill assessments:

Problem 1Difficulty: Hard
Use pi = 3.14. The dimensions of a sealed food tube are radius 5.5 yd and height 15.5 yd. Which surface area is correct?
A630.4 yd2
B725.3 yd2
C535.4 yd2
D457.7 yd2
Solution & Explanation:Use SA = 2pi r2 + 2pi rh. Substitute r = 5.5 and h = 15.5: SA = 231pi. Using pi = 3.14 gives 725.3 yd2.
Problem 2Difficulty: Hard
Use pi = 3.14. Which is the best estimate of the surface area of a cylinder with radius 4.5 ft and height 16.5 ft?
A360.3 ft2
B466.3 ft2
C529.9 ft2
D593.5 ft2
Solution & Explanation:Use SA = 2pi r2 + 2pi rh. Substitute r = 4.5 and h = 16.5: SA = 189pi. Using pi = 3.14 gives 593.5 ft2.
Problem 3Difficulty: Hard
The base of a cylinder measures 21.98 m around, and the height is 17.5 m. Use pi = 3.14 to find the total surface area.
A423.1 m2
B269.3 m2
C461.6 m2
D384.7 m2
Solution & Explanation:With pi = 3.14, the circumference formula is C = 6.28r. So r = 21.98/6.28 = 3.5. Then SA = 2pi r2 + 2pi rh = 461.6 m2.
