Find the surface area and volume OF THIS QUESTION TOO (question 99)

439.6 cm²

Step-by-step explanation:

Surface area of the cylinder is the length of the rectangular strip that goes around, and the are of the two circles

Area circle = πr²

Area circle = 3.14 * 7²

Area circle = 3.14 * 49

Area circle = 153.86

The area of both circles is 153.86 x 2 = 307.72

The rectangular strip is the diameter by the height

Diameter = 2πr

Diameter = 14*3.14 = 43.96

The strip is 43.96 x 3 = 131.88

Total surface area is 307.72 + 131.88 = 439.6
