Answer:

An angle that measures exactly 180° is known as a <u>straight</u> angle​

Step-by-step explanation:

A straight angle is basically just a line. It is equal to two right angles (which are 90 degrees) and it is also half of a circle.

I hope this was helpful! If you need any more information on straight angles or any other angles, let me know! Have a lovely day! :)

aliya0001 [1]

<u>Answer:</u>

<h2>(4, 6)</h2>

<u>Explanation:</u>

x = -4 + (12 - (-4))/2

x = -4 + (12+4)/2

x = -4 + 16/2

x = -4 + 8

x = 4

y = 2 + (10 - 2)/2

y = 2 + 8/2

y = 2 + 4

y = 6

the coordinates of the center of the circle: (4, 6)

Find the circumference and area of a circle<br>with a radius of 5 feet.​
iVinArrow [24]

Circumference = 2(pi)r

Area = (pi)r^2

r = 5

5 * 2 = 10

Circumference = 10π

5 * 5 = 25

Area = 25π

Using 3.14 as pi substitute:

5 * 3.14 = 15.7

15.7 * 2 = 31.4

Circumference = 31.4

5 * 5 = 25

25 * 3.14 = 78.5

Area = 78.5
