Can you please help me on problem 4 and 5 of my teacher created problem.

Answers

Answer 1

Answer: 4. Area of a disk of diameter D : $A= \pi*(D/2)^2\approx3.14*(3.5)^2=38.465$

Assuming that you use the usual convention of rouding 5 to the greater number :

A=38.47

5. Diameter of a circle of radius r : $A= \pi D=47$ hence $D\approx47/3.14\approx14.97$

6051 m is equal to how many km?

Answers

6,051m = 6,000m + 51m

1km=1,000 metres

--------------------------------

Therefore:

6,051 metres = 6,000/1,000km + 51/1,000km

=6,051/1,000km

=6.051km

There are 1000 meters in a kilometer. So 6000 meters would equal 6 kilometers. The remaining 51 would be put in a decimal. Our final answer is 6.051 km

Jill had a certain amount of money. she spent 15$ downloading new songs. she has 2/5 of the original amount left. how much money did she have originally?

Answers

Let's call the original amount of money x.

We know that she has 2/5 of the original amount left, and that this is equal to $15.

Therefore, 2/5(x) = 15, and x = $37.50.
