What is the height of the cone below?

v = 45 in^3

b = 5in^2

The height of the cone is h = 27

Step-by-step explanation:

Formula:-

Step 1:-

The volume of the cone is  

Given volume is V= 45 in^ 3

Given base of the cone is B= 5 in^2

Step 2:-

by using formula, we get solution

cross multiplication, we get

now simplification, the height of the cone is h = 27

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
