Answer:

The diameter would be 16

Step-by-step explanation:

The area of a circle is a=r^{2}×π. Now just plug in the values you have which is you area. 201=r^{2}×π now divide by pi on both sides you that you get about 64=r^{2}. Now find the square root on both sides which will then give you 8 as your radius. To find diameter from radius you have to multiply by 2. 8*2=16

1. A football team gains 2 yards on the first play,
Ilya [14]

Option C

The football team had a overall loss of 2 yards

<em><u>Solution:</u></em>

When the team gains yards we use a positive value, and when the team loses yards we use a negative value.

<em><u>Given that, football team gains 2 yards on the first play</u></em>

First play = +2

<em><u>Given that football team loses 5 yards on the second play</u></em>

Second play = -5

<em><u>Given that football team loses 3 yards  on the third play</u></em>

Third play = -3

<em><u>Given that football team gains 4 yards on the fourth play</u></em>

Fourth play = +4

Put the yards from four plays together, we get

⇒ 2 -5 -3 + 4

Let us simplify

⇒ -3 -3 + 4 = -6 + 4 = -2

So, -2 represents loss of two yards (since negative value indicates loss)

Simplify the expression by combining like terms:<br><br> 4n+4(2n+3)
Anna007 [38]
First, you do the distributive property on:

4(2n+3)

You would get

8n+12

Then add the original part of the equation in (4n)

4n+8n+12

Combine like terms

12n+12 is the answer
