Question

I need some help with this!

Answer 1

Answer:

A. 4.19 yd³

Step-by-step explanation:

Volume of a sphere = 4/3πr³

V = 4/3 ( 3.14) (1³)

= 4/3 ( 3.14) (1)

= 4.19 yd³

Answer 2

Answer:

$A\approx 4.19\ yd^2$

Step-by-step explanation:

The following formula can be used to find the volume of a sphere,

$A=\frac{4}{3}(\pi)r^3$

Where (r) represents the radius of the sphere or the distance from the center of the sphere to its outer edge. The term ($\pi$) represents the numerical constant ($3.1415...$). In this problem, one is given that the radius of the sphere is (1). Substitute this value into the formula and simplify to solve,

$A=\frac{4}{3}(\pi)r^3$

$A=\frac{4}{3}(\pi)(1)^3$

$A=\frac{4}{3}(\pi)1$

$A=\frac{4}{3}(\pi)$

$A\approx \frac{4}{3}*3.14$

$A\approx \frac{12.56}{3}$

$A\approx 4.19\ yd^2$
