Answer 1

Answer:

Step-by-step explanation:

3pie r cube

1386 is the ANSI I think

Answer 2

Curved surface area of sphere =
$4\pi r {}^{2}$
$4 \times 22 \ div7 \times 42 \times 42$
=22,176

volume of sphere =
$\frac{4}{3} \pi {r}^{3}$
$\frac{4}{3} \times \frac{22}{7} \times 42 \times 42 \times 42$
3,10,464
