What is the area of a circle that has a circumference of 42 inches?
a. 141.03 in2
b. 126.60 in2
c. 132.62 in2
d. 21.04 in2

First you should know the formula to find circumference of a circle:

C = 2πr

where C is the circumference and r is the radius.

We want to find the area of the circle which is A = πr^2. Thus to find the area, we need to know the radius of the circle.

Now let's plug in the value we know and solve to find the radius:

42 in = 2πr

21 in = πr

r ≈ 6.7 in

Now we plug this value in to the area formula:

A = π(6.7 in)^2

A = π(44.89 in^2)

A ≈ 141.03 in^2

Thus the answer is A.

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
