Question

Q36. The ratio of radius and height of a right circular cone is 4:9. If its volume is 1507 m³,
find its slant height and radius. (Take π = 3.14)​

Answer 1

Step-by-step explanation:

Let be the height=9@

and redius =4@

volume=1/3 πr²*h=1507m³

r²h=1439.8m3 approx

r²=1439.8/h

now put the value of r & h

16@²=1439.8/9@

@³=9.99

@=2.15

so our redius=8.6 unit

height=19.35 unit

slant=√{8.6²+19.35²}=21.17m
