Find the surface of a cylinder with a base diameter of 4yd and a height of 6yd

Pi*radius squared= area of a circle
3.14*2^2=12.56yd^2

pi*diameter=circumference
3.14*4=12.56yd

area of surface around the cylinder=circumference*height
12.56*6=75.36yd^2

area of surface around the cylinder+ (area of circle*2)= surface area
75.36+(12.56*2)=100.48

the answer should by 100.48 yards squared

hope this helps
