A line segment that joins the center of a circle to any point on the circle is called the radius of the circle. Whichever point on the circle we choose, the distance to the center of the circle will always be the same.

Find the radius if mADB=270° and length is 61.26 meters

love history [14]

Given:

In the given circle, ∠ADB = 270° and length of ADB = 61.26 m

To find the radius of the circle.

Formula

The formula to determine the radius is given by

$arc \ length =(\frac{\theta}{360})2 \pi r$

Substituting arc length = 61.26, $\theta= 270$ , we get;

$61.26 =(\frac{270}{360})2 (3.14) r$

$61.26 =4.71 r$

$13=r$

Thus, the radius is 13 m

The radius of the semicircle in the following composite figure is 8.5 millimeters. What is the total area of the composite figur

nydimaria [60]

Answer:

13.35 millimeter. (About)

Step-by-step explanation:

To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a <em>semicircle, </em>you use the the formula:

πr²/2

So, if the radius is 8.5,

8.5 · 3.14 = 26.69

Now we divide it by 2.

26.69 = 13.345

Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.
