Question

a cone is having
its base radius 12 centimetre and height 20 CM if the top of the cone is cut it off for baseball code of base radius 3 cm is revolved there every part of the solid cone because a frustum calculate the volume of frustum ​

Answer 1

Answer:

198 cube cm ⬇️⬇️

Step-by-step explanation:

volume of a frustum = 1/3πh(R^2 + r^2 + Rr)

R = 12. r. = 3. h = 20

1/3 x 22/7 (12x12 + 3x3 + 12x3)

22/21 ( 144 + 9 + 36)

22/21(189)

22 x 9

198 cube cm

Answer 2

Answer:

volume of frustum =3960cm3

Step-by-step explanation:

Radius,R=12cm

radius,r=3cm

Height,h=20cm

volume of frustum=1/3πh(R2+R2+Rr)

=1/3*22/7*20(12*12+3*3+12*3)

=440/21(144+9+36)

=440/21(189)

=440/21*189

=440*9

=3960cm3
