Question

the radius and height of a right circular cylinder is 12 cm and 16 cm find its TSA and volume in terms of pi​

Answer 1

Answer:

Surface Area , SA = 672$\pi$ Square CM

Volume, V = 2304$\pi$ Cubic CM

Step-by-step explanation:

Volume of a cylinder: V = $\pi r^{2} h$

surface area is 2π r h + 2π r²

Its Given that

Radius , r= 12 CM

Height of the Cylinder, h = 16cm

Solution:-

1) Surface area, SA =  2π r h + 2π r²

SA = (2$\pi$ x 12 x 16) + 2$\pi$ x $12^{2}$

ie SA = 384$\pi$ + 2$\pi$ x 144

SA = 384$\pi$ + 288$\pi$

SA = 672$\pi$ Square CM

2)  Volume V = $\pi r^{2} h$

ie V = $\pi 12^{2}$ x 16

V = 144$\pi$ x 16

V = 2304$\pi$ Cubic CM
