Find the circumference of a circular dog pen that has a radius of 35 meters. Use 227 for π.

220

Step-by-step explanation:

Circumference of a circle is=diameter times pi

70=diameter because diameter is twice the radius

(22/7)70 is your answer

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
