Given

The area of the circle is 1200 square inches.

To find the radius of the circle.

Explanation:

It is given that,

The area of the circle is 1200 square inches.

That implies,

\begin{gathered} Area\text{ }of\text{ }the\text{ }circle=\pi r^2 \\ \pi r^2=1200 \\ r^2=\frac{1200}{\pi} \\ r^2=381.972 \\ r=\sqrt{381.972} \\ r=19.5 \\ r=20inches \end{gathered}

Hence, the radius of the circle is 20 inches.

explain how arc length and the measure of the central angle of a circle are related. check my answer?
vovikov84 [41]
The central angle and the length of arc are related by the formula:

Length of arc = (θ/360) * 2πr

Where θ = Central angle.

If the central angle is one quarter of the entire circle, the length of arc would also be one quarter of the entire circumference of the circle.

So, the base is 20 and you will multiply the base by the height which is 15 so if you want it with the triangles and squares then, you break down the parallelogram into 2 triangles and 1 square you will get the height of the 2 triangles and the square and add them all up and you should get 300 if you need me to explain better i will!

Use this idea to find the value of x in the diagram at<br> right. Be sure to show all work.<br> 71°
EleoNora [17]

We have that  the value of x in the diagram at the right is

x=109

From the question we are told

Use this idea to find the value of x in the diagram at  right.

From The diagram  we have a Triangle with its base angles equal

Generally the equation for the Triangle   is mathematically given as

180=2b+y

Where

b=Base angles

Since Angle on a straight line is 90

Therefore

180=71+x

x=109

In conclusion

The value of x in the diagram at the right is

x=109
