4a=20⇒a=5
we know diagonals are perpendicular. if u look at one of the right triangles, you can see that for hypotenuse to be 5, the legs have to be 4 and 3 to satisfy the given ratio 4:3.
so, diagonals are 8 and 6 as we know that diagonals bisect each other.
Area=8*6/2=24
Answer:
The height of the cone is h = 27
Step-by-step explanation:
<u>Formula:</u>-
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
<u>Step 2</u>:-
by using formula, we get solution

cross multiplication, we get

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