Joe says that about 320 square centimeters of aluminum sheeting are needed to create a roll of aluminum 6 centimeters in diameter and 17 centimeters tall. Abby says it will take about 641 square centimeters. Who is correct? A. Abby is right. Joe used the wrong formula.
B. Joe is right. Abby used the height instead of the radius in her calculation.
C. Joe is right. Abby used diameter instead of radius in her calculations.
D. Abby is right. Joe forgot to add one of the bases to the total surface area.​

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

i think it is c hope that
