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,

Step-by-step explanation:
HJ ≅ JH, by symmetric property of equality.
ΔGHJ ≅ ΔIJH, by SAS congruence.
GJ ≅ IH, corresponding parts of congruent triangles are congruent.
Answer:
G
Step-by-step explanation:
Using the rule of radicals
×
⇔ 
Simplifying the radicals in the expression

= 
=
× 
= 2

× 
= 3
Then
+ 
= 2
+ 3
= 5
→ G
