If you can mow 1000 square feet per minute, how long to mow a circle with diameter of 800 feet?

Sagot :

Answer:

You can calculate the area of the circle

We know the formula is: [tex]\pi*r^2[/tex]

And if diammeter is 800, then the radio is a half: 400

We replace:

[tex]\pi*r^2 --> \pi * 400^2[/tex] [tex]\approx 502654.8[/tex]  feet

So now we can divide:

502654/1000 = 502,654 minutes
