A circle circumference is 600 M. what is the good approximation of the circle area

wlad13 [49]

Answer:

The area of the circle is 28662 M².

Step-by-step explanation:

Given:

Circumference of circle = 600 M.

Now, to find the area of the circle.

So, to get the area we need to find the radius.

By putting the formula of circumference we get the radius:

Let the radius be r.

Circumference = 2πr

$600 = 2\times 3.14\times r$ (taking the value of π = 3.14.)

$600=6.28r$

Dividing both sides by 6.28 we get:

$95.54=r$

Now, for getting the area we put the formula:

Area = πr²

$Area = 3.14\times 95.54^{2}$

$Area = 3.14\times 9127.89$

$Area = 28661.57$

So, approximately the area of the circle = 28662 M².

Therefore, the area of the circle is 28662 M².

ABC is formed by two tangents intersecting outside of a circle. If minor arc AC = 98°, what is the measure of ∠ABC?

gregori [183]

It's 82 degrees. Subtract your minor arc (98) by 360 to get your major arc, which is 262. Then, subtract 98 (minor arc) from 262 (major arc), which gives you 164. Finally, divide 164 by 2 to get angle ABC.
