If the diameter of a circle is 65 what is the area

(4225/4)pi units^2

Step-by-step explanation:

So we need to know the area of a circle formula to find the answer to this question

the formula is A = r^2(pi)

So we have the diameter but we need the radius. The radius is half the diameter so r = 65/2

Now we can plug the radius into the area formula

(65/2)^2*pi =

(4225/4)pi units^2

3318.31

Step-by-step explanation:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

answer: x=60
