A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
DENIUS [597]
The answer is 15 in³.

The volume of the cone is:
V_1= \pi r_1 ^{2}  \frac{h_1}{3} = \frac{ \pi  r_1^{2} h_1}{3}
where:
V₁ - the volume of the cone
r₁ - the radius of the cone
h₁ - the height of the cone

The volume of the cylinder is:
V_2= \pi  r_2h_2^{2}
where:
V₂ - the volume of the cone
r₂ - the radius of the cone
h₂ - the height of the cone

Since <span>the cone fits exactly inside of the cylinder, they have the same radius and the height:
r</span>₁ = r₂
h₁ = h₂

Also:
V₁ = 5

Now, let's write two volume formulas together:
V_1= \frac{ \pi r^{2} h}{3}
<span>V_2= \pi rh^{2}</span>

We can include V₂ into V₁:
V_1= \frac{V_2}{3}

⇒ V_2=3*V_1
V_2=3*5 in^{3}
V_2=15 in^{3}

Ghella [55]
Jake puts 6 stamps in his book every day.

30/6= 5 

Jake put stamps in the book for 5 days.

So, Dan puts 5 stamps in the book every day.

5*5= 25

Dan has 25 stamps when Jake has 30.

I hope this helps!

Find the compound interest on 800 at 5% per annum for 2 years.​
Ludmilka [50]

Answer:

C = 82

Step-by-step explanation:

Given

R = 5\% -- Rate

P = 800 -- Principal

N = 2 -- Time

Required

Determine the compound interest

First, we calculate the Amount (A)

A = P(1 + R)^N

A = 800*(1 + 5\%)^2

Express % as decimal

A = 800*(1 + 0.05)^2

A = 800*(1.05)^2

A = 882

The compound interest (C) is then calculated as:

C = A -P i.e. Amount - Principal

C = 882 - 800

C = 82
