Solution:
we have been given that
A police officer counted 22 revolutions of a wheel to measure the length of a skid mark. the diameter of the wheel was 15 in it mean radius is 15/2 in.
we have been asked to find how long was the skid mark in length?
As wse know that length of one revolution
So the lngth of 22 revolutions

The commutative property of addition means the order of the addends doesn't matter; we get the same sum. In symbols
<span>11 + 7 = 7 + 11, choice B, is a good illustration of commutativity.
The next part asks us to use the commutative property. Looking at the choices, we see it's not the commutative property of addition we're to use, it's the commutative property of multiplication. Let's write that generally first:
</span>
Applying that, <span>(4 + 7) * 3 = 3*(4+7), again choice B.

Answer:
<h2>The cup can hold 240π cubic centimeters of water.</h2>Step-by-step explanation:
Let's assume the cup is a cylinder. The pencil length is simulates a diagonal (hypothenuse), which forms a right triangle with the height of the cylinder and the diameter at the bottom. So, we apply Pythagorean's Theorem.
Solving for , we have
Therefore, the diameter of the cylinder is 8 centimeres, which means its radius is 4 centimeters by definition.
The volume of a cylinder is defined as
Where is the radius and
is the height. Replacing values, we have
Therefore, the cup can hold 240π cubic centimeters of water.
