Find the exact circumference of a circle with an area equal to 36 sq. in.
DochEvi [55]
The area of the circle is determined through the equation,
                                     A = πr²
Plug in the value of area
                                    36 in² = πr²       ;  r = 3.385 in
The formula for the circumference of the circle is,
                                    C = 2πr
Substitute the value of radius,
                                C = 2π(3.385 in) = 6.77π in
Thus, the circumference of the circle is 6.77π inches.

Klio2033 [76]

Sid wrapped 8 gifts.

Look at the equation Sid wrote to caclulate the cost to wrap each gift. (6.80 + 7.35) / 8. 6.80 represents the total paid for wrapping paper. 7.35 represents the total amount paid for ribbon. Knowing that information, using the equation, and knowing who Sid wrapped gifts for, we can infer Sid wrapped gifts for 8 cousins.
