Answer 1

Step-by-step explanation:

Here is the answer.

Thanks

Answer 2

Answer:

Step-by-step explanation:

V(cone) =$\frac{1}{3}$ π $r^{2}$ h

1570 = $\frac{1}{3}$ x 3.14 x $r^{2}$ x 15

r^{2} = $\frac{1570 * 3}{ 3.14* 15}$

r^{2} = 100

r = 10cm

CSA = π r l

        = 3.14 x 10 x 14

        =439.6$cm^{2}$
