Answer:

B. 434.89

Step-by-step explanation:

A basketball is a sphere and the volume formula is:

V = 4/3πr³

Given:

d = 9.4

r = 9.4/2

r = 4.7

Work:

V = 4/3πr³

V = 4/3π(4.7)³

V = 4/3π(103.823)

V = 434.89

Solve question shown below

nadezda [96]

Simplify the numerator and denominator first:

5/8 + 3/4 = 11/8

-2/3 - 5/6 = -3/2

Now you have 11/8 / -3/2

When dividing two fractions change division to multiplication and flip the second fraction over:

11/8 x -2/3 = 11 x -2 / 8 x 3 = -22/24

-22/24 reduces to -11/12

The answer is -11/12

A circular garden has a circumference of

omeli [17]

This solution to this problem is predicated on the fact that the circumference is just: $2\pir$ . A straight line going through the center of the garden would actually be the diameter, which is well known to be two times the radius of the circle, so we can say that the circumference is just:

$d\pi$

So, solving for both the radius and the diameter gives us:

$d\pi=8xy^2\pi\\ d=8xy^2\\ \\ 2\pi r=8xy^2\pi\\ r=4xy^2$

So, the length of thes traight path that goes through the center of the guardain is just $8xy^2$ , and we can use the radius for the next part of the problem.
