Answer:
4.5
Step-by-step explanation:
The equation of an area of a circle is A=πr² where r is the radius.
The radius is also half the diameter. So the radius of the quarter is 1.2
A=π(1.2)²
A=π(1.44)
A=4.52389
Well, you would have to use, "PEMDAS", (Parentheses, Exponents, Multiplication, Division, Addition, & Subtraction), which are the order of operations to go by.
So first, we do the stuff in parentheses, we'll do 1 + 2 which = 3, and the parentheses around it will = to multiplying 3 times the answer of 6 divided by 2.
So since on the order of operations Addition & Subtraction, and
Multiplication & Division could go from any order they appear on in
the problem, we'll NOW do 6 divided by 2 which equals 3, times the three from above, which will = 9, so your <span>final answer is 9. =)
</span>I hope I helped! =D
