Question

a cone has a heigth of 15 meters and a radius of 7 meters. What is its volume?

Answer 1

Answer:

769.3

Step-by-step explanation:

(  ) means multiplied

V=1/3( pi ) (7)exponent 2 for 7, (15)

Answer 2

Given,

h=15m

r=7m

now

we know the

vol. of cone=1/3πr^2h

$= \frac{1}{3} \times \frac{22}{7} \times 7 {}^{2} \times 15 \\ = > \frac{1}{3} \times \frac{22}{7} \times 49 \times 15 \\ = 22 \times 7 \times 5 \\ = > 770m {}^{3}$
