Question

The area of the base of a right cone it 154cm3 and its Volume is 308m3 Find the height and csa​

Answer 1

Answer:

height is 6 m

csa of cone is 202.75

Step-by-step explanation:

V=AB*h /3

where AB is base area

h=3*V /ab=3·308 /154=6 m

csa of cone is \pi rl

22/7*r*l

vol of cone= 1/3*pi*r^3

308= 1/3*22/7*r*r*r

7=r

slant height = root r^2 +h^2

l=9.22

csa of cone=\pi rl

22/7*7*9.22=202.75
