Answer:
452.39
Step-by-step explanation:
A=(pi)r^2
A=3.14(12)^2
A=452.39
Answer: The area of the circle is 452.16 square units.
To find the area of a circle you need to use the area of a circle formula. The formula is A= π x r^2.
π= 3.14
r= 12
The r is radius which is half of the diameter. When you apply the formula you get :
A = 3.14 x 12^2
A= 3.14 x 144
A= 452.16
The equation:
Both of your answers are correct.
Expand the equations by distributing the number outside of the parentheses. After doing the expansion, your equations are both correct.
