The diameter of a sphere is 10 in. What is the sphere's volume? Round to the nearest tenth, if necessary. A) 104.7 in3 B) 209.4
denis23 [38]
To find the volume of a sphere, you will use the formula for finding volume of a sphere. You will use the diameter to find the radius.  r = d/2, so the radius is 5 in

V = 4/3 x pi x r^3
      4/3 x 3.14 x 5^3
V = 523.6 cubic inches

The volume of this sphere is approximately 523.6 cubic inches.

The perimeter of a rectangle garden is 48 feet. The length is 5 times the width.
VARVARA [1.3K]
I'll draw a diagram for you, so that it's easier to understand. 
First you have to understand that the perimeter is all the sides add up together.

Let's set up an equation, using l for the length, and w for the width.

5w + w = 48
Simplify
6w = 48
Divide by 6 on both sides
w = 8

Now the value we got is actually both widths (the green sides), so the width is actually 4. Which means that the length is 20. 

The answer is 4ft by 20 ft.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

Add the mileage together to find total miles.

Add the hours together.

Divide total miles by total hours.

305 + 190 = 495 miles

5 + 4 = 9 hours.

495 / 9 = 55 miles per hour.

The average speed was 55 miles per hour.
