Question

Find the volumes of the following objects:
Cones
a. height = 5 cm, radius = 2 cm​

Answer 1

Answer:

20.95 $cm^{3}$

Step-by-step explanation:

Volume of cone = $\frac{1}{3}$ π $r^{2} h$

Given :  r = 2cm , h = 5cm

⇒ Volume of cone = $\frac{1}{3} (\frac{22}{7} )(2^{2} )(5)$ = $\frac{440}{21}$ ≈ 20.95 (approx.)

Answer 2

Answer:

20.95cm³

Step-by-step explanation:

Height of cone=5cm

Radius of cone=2cm

Volume of cone=1/3πr²h

=1/3×22/7×2²×5

=22/21×4×5

=22/21×20

=440/21

=20.95cm³. (approx)
