The image below is a triangle drawn inside a circle with center O:
2 answers:
The area of a circle is,
So pi times the radius squared.
~~
To find the radius we half to divide the diameter by 2 since the radius is half of the diameter.
The diameter is the line that passes through the the center of the circle going from one side of the circle to the other which is 4 in this case.
Half of 4 is 2 meaning 2 is our radius.
~~
Plug in the numbers and get,
~~
I hope that helps you out!!

Given equation : .
Strategy 1: We can cross mutiply both sides remove fraction form.
On cross multiplication, we get
x * 7 = 3 * 42
7x = 126.
Dividing both sides by 7, we get
<h3>x = 18.</h3>Strategy 2: We can find least common denominator(lcd) of both sides and multiplying both sides by that lcd to get rid denominators from both sides.
LCD of 42 and 7 is 42.
Therefore, multiplying both sides by 42, we get
x = 6 * 3
<h3>x = 18.</h3>
