Question

The area of the base of the right circular cylinder is 77 CM square and its height is 8 cm find its volume

Answer 1

Answer:

given

area of right circular cylinder =77 cm ^2

height =8cm

area of right circular cylinder =2πrh =77 cm

2 ×π r *8 =77

2 × 22\7 × 8 r =77

r = 77 \2 * 7 \22 \8

r=38.5 *12 .5

r =58.9cm

volume of cylinder = πr^2 h

22\7*58.9 ^2 ×8

=637,839.03857 *8

= 5,102,712.3086 cm cube

Answer 2

Step-by-step explanation:

GIVEN AREA OF BASE OF RHE RIGHT CIRCULAR CYLINDER =77CM2

AS BASE OF THE CYLINDER IS CIRCULAR, SO

πRsquare= 77

R square = 77/π

R square= 77×7/22

R square = 49/2

R = 7√2/2

given height = 8cm

now volume of cylinder=

πr²h

22×{7√2/2}²×8/7

616 Cm³
