The goal is to find a number between 0.125 and 0.18
1/5 is 0.2
0.2, 1.6, 0.09 are not in the range. Therefore, the square root of 0.02 (0.1414) is the answer.

I need help it is a multiple Choice question

igomit [66]

Answer:

6 m

.006 km

6,000 mm

Step-by-step explanation:

Let's look at some conversions real quick:

1 cm --> 10 mm (multiply cm by 10)

1 cm --> 0.00001 km (divide cm by 100000)

1cm --> 0.01 m (divide cm by 100)

Now that this is laid out, lets do these conversions for 600 cm.

Meters (m) = 600/100 = 6 meters

Kilometers (km) = 600/100000 = .006km

Millimeters (mm) = 600 * 10 = 6,000 mm

If the sphere shown above has a radius of 11 units then what is the approximate volume of the sphere

adell [148]

Answer:

Volume of the sphere $=5563.58units^3$

Step-by-step explanation:

Volume of the sphere= $\frac{4}{3} *\pi *r^3$

The sphere has given radius(r)= 11 units

Putting the value of the radius in the formula;

Volume of the sphere:

= $\frac{4}{3} *3.14*11*11*11$

$=1.33*3.14*11*11*11$

$=4.18*11*11*11$

$=4.18*1331$

Volume $=5563.58units^3$

The volume of the sphere with radius of 11 units is $5563.58units^3$
