Question

a rectangular paper of length 44 cm and width 6 cm is rolled to from a cylinder of height equal to width of the paper find the radius of the cylinder so rolled​

Answer 1

Answer:

radius 7 cm

Step-by-step explanation:

first first you have to find the area of rectangle it will be 264 CM then the the formula of finding the surface surface area of cylinder is equal 2× 22/7×r×h so we will divide 264 cm into 7 upon 22 into 22 into 6 equal to radius so you will get radius equal to 7cm

Answer 2

The radius of the cylinder is 7 cm

Step-by-step explanation:

A rectangular paper of length 44 cm and width 6 cm is rolled to from a cylinder of height equal to width of the paper

height of the cylinder= width of the paper = 6 cm

length of a rectangular paper becomes the circumference of the cylinder

so, circumference of the circle= 44 cm

let the radius be r cm

circumference of a circle = $2\pi r$

44= $2\pi r$

r= $\frac{44}{2\pi }$

r= 7 cm

hence, The radius of the cylinder is 7 cm
