There are many cylinders with a height of 18 meters. Let represent the radius in meters and represent the volume in cubic meters

antiseptic1488 [7]

Answer:

Step-by-step explanation:

1). Equation that represents the volume of a cylinder,

V = πr²h

Here, r = radius of the cylinder

h = Height of the cylinder

2). Fromm the given formula of volume,

r(In m) V(In cubic meters)

1 56.55

2 226.19

3 508.94

3). If the radius is doubled from 1 m to 2 m,

At r = 1 m, Volume (V₁) = 56.55 m³

At r = 2 m, Volume (V₂) = 226.19

$\frac{V_2}{V_1}=\frac{226.19}{56.55}$

= 4

Therefore, volume is not doubled when radius of the cylinder is doubled.

Question #1 What is the sum?

sweet-ann [11.9K]

Answer:

$\frac{7}{a + 8}+\frac{7}{a^2-64}$ = $\frac{14}{a^2+a-56}$

Step-by-step explanation:

Sum means finding the total of something. We can do this by using addition.

$\frac{7}{a + 8}+\frac{7}{a^2-64}$

In this problem, we will add the numerators and the denominators.

$\frac{(7+7)}{(a+8)+(a^2-64)}$

$\frac{14}{a^2+a-56}$

So, your answer is letter choice B.
