Can some one show me how to find a circumference of a circle?
Can some one show me how to find a area of a circle?

One of my question says find the circumference of a circle that has a radius of 4 cm? 
Formula: C = 2(pi)r
Your question:
C = 2(pi)4 cm = 8(pi)cm = 25.13.. cm
-------------------------
The second question says find the area of a circle that has a radius of 4 cm?
Formula: A = (pi)r^2
Your question:
A = (pi)4^2 sqcm
A = 16(pi) sqcm
A = 50.265... sqcm
