Answer:

2. 615.44 square inches

3. 314 square inches

4. 78.5 square inches

5. 254.34 square inches

Step-by-step explanation:

The area of a circle is pi*r^2, and d/2=r.

2. Since we're given the radius, pi*14^2=615.44 square inches.

3. Since we're given the diameter, pi*(20/2)^2=314 square inches.

4. Since we're given the radius, pi*5^2=78.5 square inches.

5. Since we're given the radius, pi*9^2=254.34 square inches.
