Question

a rectangular piece of paper 11cm ×4cm is folded without overlapping to make a cyclinder of height 4cm . find the volume of the cyclinder​

Answer 1

Answer:

VOLUME OF CYLINDER=36.33 CM^3

Step-by-step explanation:

CIRCUMFERENCE=2*PIE*R

           11=2*22/7*R

11*7/22*2=R

R=1.7CM

VOLUME OF CYLINDER= PIE*R^2*H

                                       =22/7*1.7*1.7*4

                                        =254.32/7

                                         = 36.33 CM^3

Answer 2

Answer:

38.5 cm3

Step-by-step explanation:

Perimeter of upper circle = 2pie r =11

2pie r = 11

2*22/7*r =11

44/7*r = 11

r = 11*7/44

r = 7/4 cm

Now Volume =pie* r square*h

= 22/7*7/4*7/4*4

=77/2 cm3

= 38.5 cm3
