C because the formula to find the are of a circle is A=(pi) * radius^2. To find the radius from diameter, just divide by two. So 60/2= 30 so now you can just plug in and 30 * 30 is 900 and 900 * pi, or 3.1415926535, is about 2827
Answer:
they are all multiples of 5
Step-by-step explanation:
when you count by five you will meet each number =D
5-10(|0.8-3/6|)
5-10(|1/5|)
5-(10)(0.2)
5-2
=3, so C would be your best answer.
Answer:
<h2><u><em>
x=3 or x=−4</em></u></h2>
Step-by-step explanation:
when a number x is added to it's square, the total is 12. find two possible values of x
x+x^2=12
x^2+x=12
x^2+x−12=12−12
x^2+x−12=0
(x−3)(x+4)=0
x−3=0 or x+4=0
x=3 or x=−4
x=3 or x=−4
