Fractions can be converted to decimals and vice versa.

<em>The decimal equivalent  of the fraction of months with 31 days is 0.583</em>

Given:

<em />Total = 12<em> --- months in a year</em>

<em />Months = 7<em> --- months with 31 days</em>

<em />

The fraction (n) of months with 31 days is:

n = \frac{Months}{Total}

So, we have:

n = \frac{7}{12}

The decimal equivalent is:

n = 0.583

Hence, (c) is correct.

The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?
soldier1979 [14.2K]

Answer:

32\pi/3 cm³

Step-by-step explanation:

If the diameter is 4 cm, then the radius is 2 cm.

Use the sphere volume formula:

V = 4/3\pir³

Plug in the radius and solve:

V = 4/3\pi(2)³

V = 4/3\pi(8)

V = 32\pi/3

So, the volume of the sphere is 32\pi/3 cm³

Can someone help with this?
Lana71 [14]

Answer:

72.1 cm

Step-by-step explanation:

The arc length formula is s = rФ, where Ф is the central angle and is in radians (not degrees).

Here we convert 140° to radians:  140°(π/180°) = 2.44 radians.

Then the desired arc length is s = rФ = (29.5 cm)(2.44 radians) = 72.1 cm
