Answer:
The area of a plate with a diameter of 9 is 63.585
Explanation:
A = πr² use 3.14 as pi
r = d
× 9 = 4.5
r = 4.5
A = 3.14 × 4.5²
A = 3.14 × 20.25
A = 63.585
Hope this helps!
63.62 inches squared
The formula for the area of a circle is πr^2
r (Radius) is half of the diameter
r = 9/2
r = 4.5in
π x 4.5^2=
π x 20.25 = 63.6172512352
to 2 dp: 63.62 inches squared.
