CONE
==============================
» If the cone has a height of 10 cm and diameter of 5 cm, what is it volume?
» Find the volume of the given cone using the formula.
- V = ⅓(πr²h) (when radius is given)
- V = ⅓(π(d/2)²h) (when diameter is given)

» Substitute the given to find the volume of the cone. Use the formula with diameter since it is the given.
- V = ⅓(π(d/2)²h)
- V = ⅓ (3.14) (5cm/2)² (10cm)
- V = ⅓ (3.14) (2.5cm)² (10cm)
- V = ⅓ (3.14) (6.25cm²) (10cm)
- V = ⅓ (3.14) (62.5cm³)
- V = ⅓ (196.25cm³)
- V = (196.25cm³) / 3
- V = 65.42cm³
ANSWER: Volume = 65.42cm³

Answer:
196.35 cm³
Step-by-step explanation:
Given: h (height) = 10cm
d (diameter) = 5cm
r (radius) = d/2
r = 5cm/2
= 2.5 cm
Volume = πr²h
= π×(2.5cm)²×10cm
= 62.5cm³π
= 196.34954084936 cm³ or 196.35 cm³
