anonymous one year ago The diameter of Z is 5 in. What is its area in terms of pi? (1 point) 2.5in.2 5in.2 6.25in.2 25in.2

1. calculusxy

Is there a certain figure that you need to find the area of ?

2. anonymous

Is Z a circular shape?

3. anonymous

yes

4. calculusxy

$A = \pi r^2$

5. calculusxy

Radius is always half of diameter 5/2 = 2.5

6. calculusxy

$A = \pi (2.5)^2$

7. calculusxy

We can have pi = 3.14 approximately

8. anonymous

so would it b c?

9. anonymous

would it be c?

10. calculusxy

Yes $6.25\pi$

11. calculusxy

We plugged in the pi since it said "in terms of pi"

12. anonymous

yes! thank you oh can you help me with another question?
