Answer 1

Answer:

hI think it's 1922...1/3πr2h...................

Answer 2

Its volume is 1570 cubic cm

Step-by-step explanation:

Circumference of base = 2 \pi r

We are given that The circumference of the base of a cone is 62.8

So,$2 \pi r =62.8$

$2 \times 3.14 \times r = 62.8$

$r = \frac{62.8}{2 \times 3.14}$

r=10

height of cone = 15 cm

Volume of cone = $\frac{1}{3} \pi r^2 h =\frac{1}{3} \times 3.14 \times 10^2 \times 15 =1570 cm^3$

Hence its volume is 1570 cubic cm
