What is the volume to the nearest tenth of cubic inch.
oee [108]

Answer:

180.6 cubic inches. (Nearest tenth is the same as 1 decimal place)

Step-by-step explanation:

The volume of a cylinder formula is:

V

=

π

r

2

h

The diameter is

10

inches, well half of the diameter is

5

inches which is the radius. Radius is half of the diameter.

If you want the diameter back, just double it.

5

+

5

=

10

.

So we can now plug the numbers into the formula.

V

=

π

(

5

2

)

(

2.3

)

V

=

π

(

25

)

(

2.3

)

(5 Squared =25)

V

=

57.5

π

But if you didn't want it in terms of

π

, so you multiply:

57.5

×

3.14

=180.55

but rounding that to the nearest tenth is the same as rounding to

1 decimal place so you get

180.6 cubic inches.
