Question

The radius of the base of a cylinder is 38 mm and its height is 51 mm. Find the surface area of the cyliner in terms of π. 6726π mm2 6764π mm2 6853π mm2 6713π mm2

Answer 1

Answer:

Choice b is correct answer.

Step-by-step explanation:

From question statement , we observe that

Radius and height of the cylinder is given.

Radius = r = 38 mm and height = h = 51 mm

We use the following formula to find surface area.

A = 2πrh+2πr² where r and h denotes radius and height of cylinder respectively.

Putting given values in above formula,we get

A = 2π(38)(51) + 2π(38)²

A = 3876π + 2888π

A = 6764π mm²

Hence, the area of cylinder is 6764π mm².
