Question

What is the CSA and TSA of Cone, Cylinder, Sphere and Hemisphere? ​

Answer 1

Answer:

CSA of cone = 2 pi r l

TSA of cone = pi r ( l + r )

CSA of cylinder = 2 pi r h

TSA of cylinder = 2 pi r ( h + r )

CSA of sphere

$= 4\pi \: {r}^{2}$

TSA of sphere

$= 4\pi \: {r}^{2}$

CSA of hemisphere

$= 2\pi \: {r}^{2}$

TSA of hemisphere

$= 3\pi \: {r}^{2}$

I hope it will help u

Answer 2

PLS MARK ME AS BRAINLIEST..

CONE:

• T.S.A =
• $\pi \: r \: (r + l)$
• C.S.A=
• $\pi \: rl$

Cylinder:

• T.S.A=
• $2\pi \: r(r + h)$
• C.S.A=
• $2\pi \: rh$

Sphere:

• T.S.A=
• $4\pi \: {r}^{2}$
• C.S.A=
• $4\pi {r}^{2}$

Hemisphere:

• T.S.A=
• $3\pi {r}^{2}$
• C.S.A=
• $2\pi {r}^{2}$
