What is the area of a circle with a circumference of 14π inches?
选项
答案
The equation for the area of a circle is A=πr2. The equation for the circumference of a circle is C=2πr. Since you are given the circumference, you can use that to find the radius, r, and then use the radius to find the area:
14π=2πr
14=2r
r=7
Now substitute r into the equation for area:
Area=π(72)
Area=49π
