Answer:

Surface area: 384.8

Volume: 538.7

Explanation:

To find the surface area we can use this formula below:

A= 2πrh+2πr²

Replace the variables:

2 · π · 3.5 · 14 + 2 · π · 3.5²

Simplify:

2 · π · 3.5 · 14 + 2 · π · 3.5² = 384.8 (rounded to the nearest 10th)

To find the volume we can use this formula below:

V= πr2

Replace the variables:

π · 3.52 · 14

Simplify: π · 3.5² · 14 = 538.7 (rounded to the nearest 10th)

π = 3.14

r = 3.5

h = 14
