The radius of a circle is the distance from the center point of a circle to the outer edge of the circle. The diameter is the distance between one point on the outside of a circle and a point on the other side, and the diameter passes through the center point.
Therefore, the diameter is just twice the radius.
We know the radius is 3.5 cm, so we can just multiply:
3.5 * 2 = 7
The diameter of a circle with a radius of 3.5 cm is 7 cm.
Hope that helped! =)

Answer:
The 20 inch pizza gives more area of pizza by 2π or about 6.28 in² more pizza.
Step-by-step explanation:
πr² is the formula for the area of a circle
Radius of the 14-inch: 7
Radius of the 20-inch: 10
7²π=
49π
49π+49π=
98π
10²π=
100π
The 20 inch pizza gives more area of pizza by 2π or about 6.28 in² more pizza.
