Use the net to find the surface area of the cylinder.
give your answer in terms of pi.

We will need calculate the area of the top, the base and  sides.
area of the top=πr²
area of the base=πr²
area of the side: 2πrh
surface area of a cylinder: area of the top + area of the base +area of the side
surface area of a cylinder=πr²+πr²+2πrh=2πr²+2πrh=2πr(r+h)

Data:
r=radius=diameter / 2=4 yd /2=2 yd
h=heigth=12 yd

Surface area of this cylinder=2π(2 yd)(2 yd + 12 yd)=4π yd(14 yd)=56π yd².

the surface area of this cylinder is 56π yd².

Sometimes life is like a tunnel. you can’t always see the light at the end of the tunnel, but if you keep moving, you will come to a better place

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
