Either my brain is straight up goneskiis or I need assistance.

olga nikolaevna [1]

The answer is C. 89 in^2

This is found by (1/2( $\pi r^{2}$ ))+70

r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5

You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.

Hope this helps!

The endpoints of a diameter of a circle are A(3,2) and B(6,6). Find the area of the circle in terms of π.

Oksi-84 [34.3K]

Answer:

area of circle in terms of π is $\mathbf{Area=6.25\:\pi }$

Step-by-step explanation:

The endpoints of a diameter of a circle are A(3,2) and B(6,6). Find the area of the circle in terms of π.

The formula used to find area of circle is: $Area = \pi r^2$

We need to find radius of circle. For finding radius we will first find diameter of circle using distance formula.

Finding distance between points A(3,2) and B(6,6) using distance formula.

$Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have $x_1=3, y_1=2, x_2=6, y_2=6$

Putting values and finding distance

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(6-3)^2+(6-2)^2}\\Distance=\sqrt{(3)^2+(4)^2}\\Distance=\sqrt{9+16}\\Distance=\sqrt{25}\\Distance=5$

So, distance is 5, we can say that diameter of circle = 5

The formula used to find area of circle is: $Area = \pi r^2$

We need radius, so we know that r = d/2 so, radius = 5/2 = 2.5

Now finding area in terms of π

$Area = \pi r^2\\Area=(2.5)^2\pi \\Area=6.25\:\pi$

So, area of circle in terms of π is $\mathbf{Area=6.25\:\pi }$

So what we do is we splie it up
remember that 1/1=1 so therefor 6/6=1
find out how many 6/6 are in 23 and how much is left over
remember that you can add the top numbers if the bottom numbers are the same
23/6-6/6=17/6 (that's one)
17/6-6/6=11/6 (that's 2)
11/6-6/6=5/6 (that's three)
therefor you have
23/6=6/6+6/6+6/6+5/6=1+1+1+5/6=3+5/6=3 and 5/6

therfor 3 goes in the blank in front of the 5/6

Quadrilateral mntu below is a parallelogram. if m∠u = 5x and m∠t = 2x – 9, what is the measure of ∠t?

frez [133]

1. A property a parallelogram must have is that adjacent angles must be supplementary, they add up to 180º. We are given the values of the adjacent angles U and T. Their sum must add up to 180º. Solve for x.
U + T = 180 
5x + 2x - 9 = 180 
7x - 9 = 180 
7x = 189 
x = 27 
Substitute this value of x for itself in angle T. 
T = 2(27) - 9 
T = 54 - 9 
T = 45, (D) is the answer
