Answer: The circumference of the circle is 53.38 cm.

Step-by-step explanation:

Circumference of the circle is the distance around the circle.

Formula used:

$C = 2\pi r$

Where,

C is circumference of circle

r is radius of circle

Given:

Radius of circle = 8.5 cm

Now putting all the given values in the above formula, we get:

$C = 2\pi r\\C=2\times 3.14\times 8.5cm\\C=53.38cm$

Therefore, the circumference of the circle is 53.38 cm.

Find the volume of the composite figure. Round your answer to the nearest hundredth

pishuonlain [190]

Answer:

The volume of the figure is 590.71 mm³

Step-by-step explanation:

To solve this problem we have to find the volume of the cylinder and the volume of the rectangular prism and add them

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 3.65mm

π = 3.14

r = radius = 3.2mm

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (3.2mm)²) * 3.65mm

v = (3.14 * 10.24mm²) * 3.65mm

v = 32.1536² * 3.65mm

v = 117.36mm³

To calculate the volume of a rectangular prism we have to use the following formula:

v = volume

w = width = 14.23mm

l = length = 10.08mm

h = height = 3.3mm

v = w * h * l

we replace the values that we know

v = 14.23mm * 10.08mm * 3.3mm

v = 473.347mm³

we add the volumes

v = 117.36mm³ + 473.347mm³

v = 590.707

round to the neares hundredth

v = 590.707 mm³ = 590.71 mm³

The volume of the figure is 590.71 mm³

Answer:

<h2>The value of $n$ is 31 years.</h2>

Step-by-step explanation:

The given equation is formed by different variables, where $n$ indicates the period of time in years where the rate of inflation is calculated.

In this case, we have a period from 1980 to 2011. The difference between these years would be the period of time used to find the inflation rate.

$2011-1980=31$

Therefore, the value of $n$ is 31 years.
