Asphere which has a diameter of 6 inches has a volume of:
earnstyle [38]

Answer:

9.42 cubic inches

Step-by-step explanation:

In order to find the volume for a sphere, we use the formula V = πr. For the sake of simplicity, we will be using 3.14 for π. Before we plug anything in, let's get our radius. Remember, the radius is half of the diameter.

Equation: d = 2r

Replace: 6 = 2r

Divide: 3 = r

Now that we have our radius, let's plug in what we have and solve.

Equation: V = 3.14r

Replace: V = 3.14(3)

Multiply: V = 9.42

Remember, volume is measured in cubic units, so use cubic inches for the unit here.

An art classroom has 5 boxes with sharpie pens and clipboards. Each box has 4 sharpies there are 25 supplies in all how many tot
Step2247 [10]

Answer:

1 clipboard per box

Step-by-step explanation:

First, multiply 4 by 5 (because we need to see how many supplies there are already taken up)

4x5= 20

Next, subtract 25 from 20 (to see how many total clipboards there are)

25-20= 5

Since there are 5 boxes, we divide the number of clipboards(5) by the number boxes(5):

5/5= 1
