Answer:

$d=\frac{2w(c-2)}{5}$

Step-by-step explanation:

The given formula is:

c=5d+4w/2w

We need to find d.

Multiply 2w on both sides, we get

c x 2w= 5d+4w/2w x 2w

2cw=5d+4w

Adding -4w on both sides, we get

2cw-4w=5d+4w-4w.

2cw-4w=5d

2w(c-2)=5d

Dividing by 5, we get

2w(c-2)/5 = 5d/5

2w(c-2)/5 = d

Hence the required formula with subject d is

$d=\frac{2w(c-2)}{5}$

The volume of a sphere is a function of its radius, V=4/3 πr^3 Evaluate the function for the volume of a volleyball with radius

il63 [147K]

The volume of a volleyball with radius 11.1 cm is 5731.025 cubic centimeter

<h3>Solution:</h3>

Given that volume of a sphere is a function of its radius

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

Radius = 11.1 cm

To find: volume of a volleyball

Since volleyball is generally of spherical shape, we can use volume of sphere formula

$\text {volume of sphere }=\frac{4}{3} \pi r^{3}$

Where "r" is the radius of sphere and $\pi$ is a constant which has value 3.14

Substituting the given radius r = 11.1 cm

$\text {volume of sphere }=\frac{4}{3} \times \frac{22}{7} \times 11.1^{3}$

$\text {volume of sphere }=\frac{88}{21} \times 1367.631$

volume of sphere = 5731.025 cubic centimeter

Thus the volume of volleyball is 5731.025 cubic centimeter

Answer:

152 in^2

Step-by-step explanation:

If you take the left side and consider it a whole rectangle, you can calculate the area of that triangle to be 80. Using the same method, you can find the area of the rectangle of the right to be 72. Then add them together.

80 + 72 = 152 in^2
