Answer:
A =63.585 in^2
Step-by-step explanation:
The area of a circle is found by
A = pi r^2
A = pi (4.5)^2
A = pi(20.25)
We can approximate pi by 3.14
A = (3.14) (20.25)
A =63.585 in^2
Answer:no cap
Step-by-step explanation:that looks complicated
OPTION D = 2q is right answer
Answer:
Step-by-step explanation:
Diameter=5 inches
Area= π![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
<u>r is the radius of coaster.</u>
<u>Radius=diameter/2</u>
Substitute the value of D:
r=5/2
Now
Area=π ![\frac{5}{2} ^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D%20%5E%7B2%7D)
Area=π(
)
Area=12.5π sq.inches
