Question

The volume of the vessel in the form of a right circular cylinder is 448π^3 cm, and its height is 7 cm. Find the 2. radius of its base.
​

Answer 1

Answer:

Volume of a Cylinder of Radius R and height h =πR

2

h

∴ volume of the given cylinder =π×R

2

×7=448πcm

3

R

2

=64

R=8cm

Curved surface area of a cylinder of radius "R" and height "h" =2πRh

∴ curved surface area of the given cylinder =2×π×8×7=112π cm

2

plz mark me as brain list

Answer 2

Answer:

112cm

Step-by-step explanation:

Volume of a Cylinder of Radius R and height h =πR

2

h

∴ volume of the given cylinder =π×R

2

×7=448πcm

3

R

2

=64

R=8cm

Curved surface area of a cylinder of radius "R" and height "h" =2πRh

∴ curved surface area of the given cylinder =2×π×8×7=112π cm
