Circumference=2pi*r
20.7=2pi*r
r=3.296 or 3.3
A=pir^2
a=34.1946 or about 34.19

Hey!

Circumference = 20.7 cm
Circumference of circle= 2πr


20.7= 2×3.14×r
20.7=6.28×r
20.7/6.28= r
r= 3.29 cm

Area of circle = πr^2
Area= 3.14×3.29×3.29
Area= 33.98 cm^2

Hope it helps...!!!

<h2>A = 0.625</h2>

There are 8 points between 1 and 0 so divide 1 by 8.

1 / 8 = 0.125

Each point has a value of 0.125.

You can minus 0.125 from 1 until you reach A.

Or you can multiple 0.125 by the number of points from 0 to A, including A.

1 - 0.125 - 0.125 - 0.125 = 0.625

0.125 * 5 = 0.625

<h2>A = 0.625</h2>

I will give you 100 points if you can answer this<br><br> (66×578)÷3368=55÷77=???
erma4kov [3.2K]
(66✖️578) ➗ 3368=55➗77

P parentheses
E exponents
M multiplication
D division
A addition
S subtraction

You would do (66✖️578) first since it is in parentheses
66✖️578=38,148

38,138➗3368=55➗77
Since there are no exponents or multiplication you would do division

38,138➗3368= 11.3236342
55➗77=0.7

11.32 does not equal 0.7
So this equation would be false

Hope this helps! :3
