Answer:
3.98 cm, 602.18 cm²
Step-by-step explanation:
<u>Given:</u>
<u>To find:</u>
<u>Solution:</u>
- V = πr²h
- h = V/πr² = 800/(π8²) = 3.98 cm
- S = 2πr (r+h) = 16π(8+3.98) = 602.18 cm²
The formula for calculating the height is h = 3V/πr²
<h3>Subject of the formula</h3>
The formula given is the formula for calculating the volume of a cone
V = 1/3πr²h
where
h is the height
r is the radius
Make h the subject of the formula
Cross multiply
3V = πr²h
Divide both sides by πr²
3V/πr² = πr²h/πr²
h = 3V/πr²
Hence the formula for calculating the height is h = 3V/πr²
