Answer:
The height of the cone is
Step-by-step explanation:
we know that
The volume of a cone is equal to
In this problem we have
----> the radius is half the diameter
assume
substitute the values and solve for h
Answer:
account after 2 years of simple interest at 10%: (2,500 * 0.10 * 2) + 2500 = 3,000
Note that simple interest only pays interest on the original balance, NOT on the accrued (paid) interest....
a) 5 more years at 10% simple: (2500 * 0.10 * 5) + 3,000 = $4,250
or
5 years compound interest on $3k: 3,000(1.07^5) = $4,207.66
b) TOTAL of 10 years
simple interest: (2500 * 0.10 * 10) + 2500 = 5,000
compound interest: only 8 years remain of the total 10 year time horizon
3000(1.07^8) = $5,154.56

Answer:
h = 3 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the height )
Here A = 7 = ← expressed as an improper fraction
and b = 5 = , thus
× × h = , that is
h =
Multiply both sides by 8 to clear the fractions
21h = 63 ( divide both sides by 21 )
h = 3
