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
