Question

a cylinder has base radius 12cm,height15cm,find its.base area,C.S.A,T.S.A.,valume​

Answer 1

Answer:

radius = 12cm. , height= 15cm

curved surface area of cylinder =2πrh

2×3.14×12×15. {π = 3.14

= 1130.4

total surface area of cylinder =2πr(h+r)

2×3.14×12(15+12)

= 20347.2

Answer 2

Step-by-step explanation:

here ,

R=12 cm

H=15 cm

Base area of the cylinder= πr^2 sq.units

=3.14*12*12

=3.14*144

=452.16 sq.units

C.S.A of the cylinder = 2πrh sq.units

=2*3.14*12*15

= 6.28*180

=1130.40 sq.units

T.S.A of the cylinder = 2πr(h+r)sq.units

= 2*3.14*12(27)

=6.28*324

= 2034.72 sq.units

Volume of the cylinder=πr^2h

=3.14*12*12*15

=3.14*144*15

=6782.40 cu.units
