Circumference formula tells you C=2 \pi r

<span>C=2 \pi r
</span><span>138.16=2 \pi r
</span>21.99= r
<span>r=21.99cm</span>
The formula to find the area of a circle is A= \pi r^2

<span>A= \pi r^2
</span><span>A= \pi (21.99)^2
</span><span>A= \pi (483.56)
</span>A= 1519cm^2

Flura [38]
The answer is C <<<=====
It can't be anything else. It is not a right angle. A>90
It can't be acute because one angle is greater than 90.
It can't scalene because at least 2 of the angles (and 2 sides) are equal.

Find the area of the regular polygon 7 in​
nata0808 [166]

Ummmm that’s a triangle but I guess I’ll solve for both 7x7= 49/2= 24.5 triangle. Polygon is different but I guess if the perimeter and line to the center is both 7 okay 7x5= 35x7= 245/2= 122.5 cause triangle is wxL /2 and polygon is AxP/2 soooo I hope this helped

a_sh-v [17]
Hi there!

Let x=1

X-3y=6
1-3y=6
-3y=6-1
-3y=5
Y=-5/3

Therefore a point would be (1, -5/3)

Hope this helps!

Look at the picture! Express the following set in set-builder notation ?
Alex

Answer:

A.   E={x|x\in N and x is a multiple of 8}

Step-by-step explanation:

Let x represent the set of natural numbers. Then we can write;

x\in N.

The set of all natural numbers that are multiples of 8 is then written as;

x\in N and x is a multiple of 8.

E is the set of natural numbers that are multiples of 8 can then be written in set builder notation as;

E={x|x\in N and x is a multiple of 8}

The correct choice is A
