answer is:
Circum: 25.13274 cm^2
Area: 50.26548 cm^2
Step-by-step explanation for the CIRCUMFERNCE ONLY:
Original equation for the circumference of a circle:
C=2(pi)r
We will use 3.14 as pi
We know that the diameter of a circle is 2 times the radius, so in order to find the radius all we have to do is divide the diameter by 2.
8/2 = 4
So now we know what the radius is equal to.
4
So now just plug in your numbers to the original equation
2 X (3.14) X 4
25.13274
If we were to round up the answer would be
25.13
Hope this helps!
