1.  1m=100 cm
1m^2= 10,000 cm^2

2.  if 3 pencils are 1.65, then 1 pencil is 1.65/3=$ 0.55
7 pencils will cost 7* $0.55= $3.85

3.1 ha is 10,000 m^2, and 1 soccer filed is roughly 100m *110 m
so it makes sense that 1 ha is roughly 2 tennis courts
4.odd numbers between 20 and 30 are
21,23,25,27,29
lets add the,m
21+23+25+27+29=125

____ [38]

Answer:

About 50.14 Centimeters

Step-by-step explanation:

The formula for the volume of a cylinder is:

\pi(r^2)h

Now, let's plug in the values. (We'll use 3.14 for pi.)

3.14(r^2)76 = 600,000

All we do now, is solve for r. Divide 76 on both sides...

3.14(r^2) = 7894.74

Divide 3.14 on both sides...

r^2 = 2514.25

Lastly, find the square root on both sides.

\sqrt{r^2} = \sqrt{2514.25}

r = 50.14

Therefore, the r, or the radius, is around 50.14 centimeters. Hope this helps!
