HELP PLEASE IT WAS DUE 10!!!

A bakery makes cylindrical mini muffins that measure 2 inches in diameter and one and one fourth inches in height. If each mini muffin is completely wrapped in paper, then at least how much paper is needed to wrap 6 mini muffins? Approximate using pi equals 22 over 7.


A- 14 and 1 over 7 in2

B -23 and 4 over 7 in2

C -47 and 1 over 7 in2

D - 84 and 6 over 7 in2

A,B,C,D which one

Answer 1

Explanation:

Surface area of a cylinder = 2πr(r + h)

radiius = 1/2 diameter so the radius is 1/2 of 2 = 1

Surface are = 2(22/7)(1 )[(1 + 1.25)]

44/7 (2.25) = 99/7

This is for ONE muffin - mulitply by 6 to find out how much paper for

6 muffins,

6 × 99/7 = 594/7 = 84 6/7 in²
