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 $5:3$ .

3/2y-3+5/3 when y=6 and z=3

marissa [1.9K]

Answer:

$5 \frac{1}{3}$

Step-by-step explanation:

Assuming We want to evaluate

$\frac{3}{2y - 3} + \frac{5}{3} z$

When y=6 and z=3.

We substitute to get:

$\frac{3}{2 \times 6 - 3} + \frac{5}{3} \times 3$

We multiply to get:

$\frac{3}{12 - 3} + \frac{15}{3}$

We simplify the denominator to get:

$\frac{3}{9} + \frac{15}{3}$

Reduce the first fraction:

$\frac{1}{3} + \frac{15}{3}$

Add the numerator and keep one denominator for they are like fractions

$\frac{16}{3}$

Write as a mixed number:

$5 \frac{1}{3}$

Slove this question c^2-81=0

Firdavs [7]

To solve a square root, get the ^2 on one side and the 81 on the other side.
add 81 to both sides.

c^2 = 81
to clear the power of 2, take the square root of both sides.
c = + - sqrt81
c = + - 9
c = 9 and c = -9
