Question

HELP PLEASE!=)The circumference of a circle is 50.24 centimeters. Find the area of the circle. (Use 3.14 for π.)

Answer 1

well what is the circumference of a circle? the formula?

Answer 2

circumference,C = 2 *pi*r = 50.24
pi*r=50.24/2 = 25.12
\[area = (Pi times r)^{2}\/Pi]
area = 25.12*25.12/3.14= 200.96...

Answer 3

circumference is 50.24 and the forula is A=pi*radius^2

Answer 4

Circumference = 2*pi*r

to find your radius...you divide 50.24 by 2....then divide it again by 3.14

now you have the radius..

to find the AREA...use your equation A = pi * r²

and then you will have your area

Answer 5

50.24 divided by 2 is25.12 = 12.56... 3.14 *12.56^2= 495.. ?

Answer 6

where did 12.56 come from?

you divided the 50.24 by 2...good....by then divide THAT number by pi..(3.14)

Answer 7

8

Answer 8

right...that's your radius

now plug THAT in for "r" in your area formula

Answer 9

12.56 was when i divided 25.12 by 2. my mistake

Answer 10

200.96 =)

Answer 11

there you go :)

Answer 12

thank you for helping me through it! :D
