Answer:
height = 18m
Step-by-step explanation:
cone volume = 3183.96 m³
1/3 πr²h = 3183.96
1/3×3.14×13×13×h = 3183.96
h = 3183.96×3/13×13×3.14
h = 9551.88/530.66
h = 18
He reads 1/11 book in 2/5 hour.
A whole book is 11/11 of a book.
Multiply by 11.
He reads 11/11 book in 11 * 2/5 hour.
He reads 1 book in 22/5 hour.
22/5 hour = 4.4 hour = 4 hours and 24 minutes
