A deli is trying out new labels for their cylindrical-shaped wheels of cheese. The label covers the entire wheel except the circular top and bottom.

If the wheel has a radius of 30 centimeters and a height of 20 centimeters, how many square centimeters of the wheel does the label cover? (Approximate using pi equals 22 over 7)

792,000 over 7 square centimeters
66,000 over 7 square centimeters
26,400 over 7 square centimeters
2,640 over 7 square centimeters

Answer 1

Answer: Letter C

Explanation:

26400/7 cm

Lateral surface area of a cylinder:A = 2πrh,

Given:π = 22/7, r = 30 cm, h = 20 cm

Substitute and calculate:A = 2 * 22/7 * 30 cm * 20cm = 26400/7 cm²

Answer 2

C) 26400/7 cm²

---------------------------

Lateral surface area of a cylinder:

• A = 2πrh,

Given:

• π = 22/7, r = 30 cm, h = 20 cm

Substitute and calculate:

• A = 2 * 22/7 * 30 cm * 20cm = 26400/7 cm²

The matching choice is C.
