Answer: 16π

Step-by-step explanation:

First, solve for total area:

A = πr^2

A = π(8^2) = 64π

Then, find 1/4 of the area of the whole (since this is only a quarter circle)

A/4 = (64π)/4 = 16π

vazorg [7]

Answer:

O C. 0

Step-by-step explanation:

What is the sum of 15 and its additive inverse?

In Mathematics, the additive inverse of a number is defined as the number that when it is added to a specific number equals 0

From the above question, the additive of 15 = -15

Therefore, the sum of 15 and its additive inverse is calculated as:

15 + -15

= 15 - 15

= 0

Therefore, Option C is the correct option

Do the ratios 4/2 and 10/5 form a proportion? Yes or no
mars1129 [50]

Answer:

These are both 20 so that means that this is proportional, yes.

Step-by-step explanation:

Hi.

To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.

Here is how we do this.

\frac{4}{2}    \frac{10}{5}

So basically what we are doing is multiplying across in a diagonal direction.

Diagonal meaning like a slash / .

So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.

Do the same for the 2 and the 10.

So we have to multiply :

4 x 5

2 x 10

=

20

These are both 20 so that means that this is proportional, yes.

Hope this helps.

If you have any questions or concerns feel free to message me.

slava [35]

Answer:

see explanation

Step-by-step explanation:

1 revolution is equivalent to the circumference of the wheel

1 revolution = πd ( d is the diameter )

                    = 70π cm

50 revolutions = 70π × 50 = 3500π cm = 35π m ≈ 110m ( nearest metre )
