You can put this solution on YOUR website! Find the surface area of a can of energy drink with a diameter of 8 cm and a height of 10 cm.
Round to two decimal places.
:
The surface area is the area of he two ends 2(pi*r^2) plus the vertical
area which is the the circumference (2pi*r) times the height (h)
:
A = 2(pi*r^2) + (2*pi*r*h)
In this problem, r:*8 = 4 cm; and h = 10
A = 2(pi*4^2) + (2*pi*4*10)
A = 100.531 + 251.327
A = 351.858 rounds to 351.86
