Question

& Find the volume, curved surface area and the total surface area of
cone having se radius 35 cm and heights 12cm​

Answer 1

Answer:

answers are given for the given problem

Answer 2

IT IS GIVEN THAT RADIUS OF CONE =35CM

HEIGHT OF A CONE =12 CM

SO HERE FIRST WE HAVE TO FIND LENGTH=?

SO,L SQUARE =R SQUARE + H SQUARE

L SQUARE = 35 SQUARE + 12 SQUARE

L SQUARE = 1225+144

L SQUARE=1369

SO,L=37 CM

NOW VOLUME OF CONE =1/3*π*R SQUARE *H

VOLUME OF CONE =1/3*22/7*35*35*12

SO,VOLUME OF CONE=15400 CM CUBE

NOW CSA OF CONE =?

CSA OF CONE=π*R*L

CSA OF CONE =22/7*35*37

CSA OF CONE =4070 CM SQUARE

NOW,TSA OF CONE=πR(L+R)

TSA OF CONE = 22/7*35*72

TSA OF A CONE = 7920 CM SQUARE

S0,CSA=4070 CM SQUARE , TSA =7920 CM SQUARE AND VOLUME =15400 CM CUBE
