The radius r of a sphere is increasing at a constant rate of 0.04 centimeters per second. (Note: The volume of a sphere with rad

-Dominant- [34]

Answer:

The rate of the volume increase will be $\frac{dV}{dt}=50.27 cm^{3}/s$

Step-by-step explanation:

Let's take the derivative with respect to time on each side of the volume equation.

$\frac{dV}{dt}=4\pi R^{2}\frac{dR}{dt}$

Now, we just need to put all the values on the rate equation.

We know that:

dR/dt is 0.04 cm/s

And we need to know what is dV/dt when R = 10 cm.

Therefore using the equation of the volume rate:

$\frac{dV}{dt}=4\pi 10^{2}0.04$

$\frac{dV}{dt}=50.27 cm^{3}/s$

I hope it helps you!

A map has a scale of 2 cm: 11 m. The actual distance x from point A to point B, if these two points are 12

ahrayia [7]

9514 1404 393

Answer:

B. 66 m

Step-by-step explanation:

Map and ground distances are proportional:

ground/map = ground/(12 cm) = (11 m)/(2 cm)

ground = (12 cm)(11 m/(2 cm)) = 66 m

The distance from A to B is 66 m.

For each 24 mm of coloured fabric Gordon uses to make his curtains, he also uses 1.2 cm of white fabric. Express the amount of w

swat32

Answer:

1 : 2

Step-by-step explanation:

Given that,

amount of coloured fabric Gordon use to make his curtain = 24mm

amount of white fabric Gordon use to make his curtain = 1.2cm

To find,

ratio of the amount of white fabric to coloured fabric

1 cm = 10mm

1.2 cm = 1.2 * 10

= 12 mm

<h3>Ratio</h3>

12 / 24

1 / 2

1 : 2

So, ratio of the amount of white fabric to coloured fabric is 1 : 2

The weight of the circle that is double the weight of the triangle is 20 grams.

<h3>How to find weight ?</h3>

The weight of the rectangle is 80 grams.

The weight of the triangle is double the weight of the weight of the circle.

A rectangle is made up of 2 triangles. Therefore,

weight of each triangle = 80 / 2 = 40 grams

Since, the weight of the triangle is double the weight of the circle, the weight of the circle can be calculated as follows:

weight of circle = 40 / 2

Therefore,

weight of the circle = 20 grams.
