3. a circle has a diameter of 10 meters.

a. what is the circumference of the circle?

b. what is the radius of the circle?

c. what is the area of the circle?

Step-by-step explanation:

a) The circumference is C = pi*d, or pi*10 meters.

b) The radius of the circle is half the diameter, and that comes out to 5 meters.

c)  The area of this circle of radius 5 meters is A = pi*(5 m)^2 = 25*pi m^2.
