Question

PLS HELP ITS URGENT!!


The circumference of the ball is 9. 4 inches. What is the approximate surface area and volume of the ball? Round your answers to the nearest unit.

The surface area of the ball is approximately

square Inches.

The volume of the ball is approximately

cubic Inches.

Answer 1

2(pi)r = 9.4in
(pi)r = 4.7in
3.14r = 4.7in
r = 1.497in

Surface Area Of a Sphere = 4(pi)r^2 = [4(3.14)(1.497)^2]in^2 = 28.147in^2 = 28in^2
Volume Of a Sphere = 4/3(pi)r^3 = [4/3(3.14)(1.497)^3]in^3 =14.05in^3 = 14in^3
