The height of a right circular cylinder is 1.5 times the radius of the base. What is the ratio of the total surface area to the

Naily [24]

Let r represent the radius of cylinder.

We have been given that the height of a right circular cylinder is 1.5 times the radius of the base. So the height of the cylinder would be $1.5r$ .

We will use lateral surface area of pyramid to solve our given problem.

$LSA=2\pi r h$ , where,

LSA = Lateral surface area of pyramid,

r = Radius,

h = height.

Upon substituting our given values in above formula, we will get:

$LSA=2\pi r\cdot (1.5)r$

Now we will find the total surface area of cylinder.

$TSA=2\pi r(r+h)$

$TSA=2\pi r(r+1.5r)$

$TSA=2\pi r(2.5r)$

$\frac{TSA}{LSA}=\frac{2\pi r(2.5r)}{2\pi r(1.5r)}$

$\frac{TSA}{LSA}=\frac{2.5r}{1.5r}$

$\frac{TSA}{LSA}=\frac{25}{15}$

$\frac{TSA}{LSA}=\frac{5}{3}$

Therefore, the ratio of total surface area to lateral surface area is $5:3$ .

Simplify square root of five times the quantity eight plus three square root of six.

aev [14]

Answer:

$8\sqrt{5}+3\sqrt{30}$

Step-by-step explanation:

we have the expression

$\sqrt{5}(8+3\sqrt{6})$

Apply the distributive property

$8\sqrt{5}+3(\sqrt{5})(\sqrt{6})$

$8\sqrt{5}+3\sqrt{30}$

therefore

eight square root of five end root plus three square root of thirty

The interquartile range is the difference between the upper quartile and the lower quartile.

• The upper quartile is the line that is on number 22 on the number line
• The lower quartile is the line that is on number 16 on the number line

22-16 = 6 and that’s your IQR!
