Answer 1

`\huge\boxed{\sf SA \approx 967.1\ cm\²}`

Explanation:

Given data:

Radius = r = 7 cm

Height = h = 15 cm

Required:

Surface Area = SA = ?

Formula:

Surface Area of a cylinder = 2πrh + 2πr²

Solution:

Using 3.14 for π

Now, Put the given data in the above formula.

SA = 2(3.14)(7)(15) + 2(3.14)(7)²

SA = 659.7 + 2(3.14)(49)

SA = 659.4 + 307.72

SA ≈ 967.1 cm²
