The volume of a golf ball is approximately 4in.3 what is the diameter round you answer to the nearest whole number

marin [14]

Answer:

D. 2 inches.

Step-by-step explanation:

Given the following data;

Volume of golf (sphere) = 4 in³

A golf ball is spherical in shape. Thus, to find its volume we would use the formula for the volume of a sphere.

$Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}$

Substituting into the equation, we have;

$4 = \frac {4}{3} * 3.142* r^{3}$

Cross-multiplying, we have;

$12 = 4 * 3.142* r^{3}$

$12 = 12.568 * r^{3}$

$r^{3} = \frac {12.568}{12}$

$r^{3} = 1.0473$

Taking the cube root of both sides, we have;

Radius, r = 1.016 inches.

To find the diameter;

Diameter = radius * 2

Diameter = 1.016 * 2

Diameter = 2.03 ≈ 2 inches.

The scale from a map to actual distance is 2.5 cm to 620 mi. The distance on the map between Chicago and Boston is about 3.5 cm.

swat32

Answer: 868 miles

Step-by-step explanation:

Given: The scale from a map to actual distance is 2.5 cm to 620 miles.

i.e. 1 cm on map = $\dfrac{620}{2.5}\text{ miles}=248 \text{ miles}$

If the distance on the map between Chicago and Boston is about 3.5 cm.

Then, the actual distance between them = $3.5\times 248 \text{ miles}=868 \text{ miles}$

Hence, the approximate distance between Chicago and Boston = 868 miles.

The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child is 3 years older than t

kondaur [170]

Answer:

the oldest sibling is 12 years old.

The middle child is 9 years old.

The youngest child is 6 years old.

Step-by-step explanation:

Let the age of the youngest child be x

Then the oldest child will be 2x.

The middle child will be x + 3.

Since the combined age is 27;

x + 2x + x + 3 = 27

4x = 27 - 3

x = 24 / 4

x = 6

now 2x = 12 and x + 3 = 9
