A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of 2π/3

Aleksandr-060686 [28]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Radius of circle = 10 inches

Central angle is given by

$\frac{2\pi }{3}$

As we know the formula for " Length of an arc " :

Length of arc is given by

$l=r\theta\\\\l=10\times \frac{2\pi}{3}\\\\l=10\times \frac{2}{3}\times \frac{22}{7}\\\\l=20.95\ inches$

Hence, length of an arc is 20.95 inches.

Hence, Option 'C' is correct.

If a cylinder with height 9 inches and radius rr is filled with water, it can fill a certain pitcher. How many of these pitchers

katrin2010 [14]

Answer:

9 pitchers

Step-by-step explanation:

Given

Cylinder 1:

$Radius = r$

$Height = 9$

Cylinder 2:

$Radius = 3r$

$Height = 9$

Required

How many pitchers' cylinder 2 can fill

First, we calculate the volume of both cylinders

Volume is calculated as:

$Volume = \pi r^2h$

For A:

$V_A = \pi r^2*9$

$V_A = 9\pi r^2$

For B:

$V_B = \pi (3r)^2 * 9$

$V_B = \pi *9r^2 * 9$

$V_B = 9* 9\pi r^2$

In (a): $V_A = 9\pi r^2$

So, we have ve:

$V_B = 9*V_A$

$V_B = 9V_A$

<em>If the first cylinder can fill 1, then the second can fill 9 pitchers</em>

How do you estimate 52% of 84?

Nastasia [14]

The way to answer this question is to first make 52% into a decimal:

52% = 0.52

so now we will simply multiply:

84
x.52

once you have multiplied these numbers it comes out to be 43.68.
So your answer is 43.68.

Hope this answer helps! feel free to ask any additional questions :)
