Question

Two circles have the same radius. Complete the description for whether the combined area of the two circles is the same as the area of a circle with twice the radius.

The combined area of two circles with the same radius is __________ πr2. The area of a circle with twice the radius is __________ πr2. The combined area of two circles is ______ as the area of a circle with twice the radius.

Answer 1

1. Is 2 because your combining the area or circles

2. D (Diameter) because Diameter is the equivalent of 2 radius since the circles has the same radius it is correct

Answer 2

The combined area of two circles with the same radius is 2 πr². The area of a circle with twice the radius is 4 πr². The combined area of two circles is not the same as the area of a circle with twice the radius.
