DUE IN 3 MINS PLEASE HELP WITH PART 2, ALR SOLVED PART1. 25 POINTS
Diameter = 9/2 yd

Answer 1

Answer:

1) $\displaystyle V=\frac{4}{3} \pi (\frac{9}{4} )^3$

2) V = 15.2π yd³

Step-by-step explanation:

       To find the volume of the sphere, we will substitute into the formula for the volume of a sphere. The radius (r) is half of the diameter (d). Nine-halves divided by two is nine-fourths.

Volume of a sphere:

    $\displaystyle V=\frac{4}{3} \pi r^3$

Substituting the radius:

➜ This gives us part 1.

    $\displaystyle V=\frac{4}{3} \pi (\frac{9}{4} )^3$

Cube:

    $\displaystyle V=\frac{4}{3} \pi (\frac{729}{64} )$

Multiply:

    $\displaystyle V=\frac{2916}{192} \pi$

Divide:

➜ This gives us part 2.

   V = 15.1875π
