Question

find the volume and surface area of the sphere of diameter 35 cm.

Answer 1

Answer:

V ≈ 179,666.7 cm³ , A ≈ 15,400 cm²

Step-by-step explanation:

V = $\frac{4}{3}$ π r³

Surface A = 4 π r²

~~~~~~~~~

V ≈ $\frac{4}{3}$ ( $\frac{22}{7}$ ) (35)³ =  $\frac{4}{3}$ ( $\frac{22}{7}$ ) × 42,875 ≈ 179,666.7 cm³

Surface A ≈ 4( $\frac{22}{7}$ )(35)² = 4( $\frac{22}{7}$ ) × 1,225 = 15,400 cm²
