First, find the radius of the circle. The radius of a circle is half the diameter. r=13/2=6.5
Second, use the equation A=pi * r^2 to find the area of the circle.
A=(3.14) * (6.5^2) = 132.665m^2
so the answer is 132.7 m^2.
Answer:
a = 9
Step-by-step explanation:
a^2 = 41^2 - 40^2
a^2 = 1681-1600 = 81
a = 9
Answer:
2
Step-by-step explanation:
If this product was written as an equation, it would look like this:
16 - 7 * 2
PEMDAS states that multiplication comes before addition. So, the first step in the equation is to multiply 7 and 2.
7 * 2 = 14
Now, the equation looks like:
16 - 14
All we need to do now is subtract 14 from 16.
16 - 14 = 2
So, the final answer is 2.
