B. Suppose you have two cans of paint, which will cover a total of 800 ft squared find the radius of the largest circle you can paint round to the nearest tenth of A foot

**John**, Thursday, April 12, 2012 at 10:22pmFor the area of a circle is πrē as you stated so all you do is set 400 equal to πrē and solve for r.

400=πrē/π

127.32=rē

√127.32)= r

r=11.3

Same thing for this except you use 800 instead of 400 so.

800=πrē

254.64=rē

√254.64)= r

r=15.9 or 16.0 for rounding purposes.
