Question

Q26. A Cone has the height 16cm. and radius 12cm., find C.S.A. and T.S.A. of the Cone. (TT = 3.14)​

Answer 1

Answer:

CSA=753.6 sqcm

TSA=1205.76 sqcm

Step-by-step explanation:

C.S.A=pie×R×L(L=slant height)

L^2=H^2+R^2=256+144=400

L=20 cm

now CSA=3.14×20×12=753.6 sqcm

TSA=pie ×R(R+L)

TSA=3.14×12×(12+20)

TSA=3.14×12×32=1205.76 sqcm
