A^2 + B^2 = C^2.
so 49 + 576 = C^2
625 = C^2
Now find the square root of 625.
25 = C (in your case r)
The radius is 6 inches the diameter is 12 inches
Simplify 8/10
(4*2)/(5*2)
2/2=1
Thus,
8/10=4/5
Now, compare 4/5 and 3/5.
Hope this helps!
Answer:

Step-by-step explanation:
Given that,
Length of a rectangle, 
Width of a rectangle, 
We need to find the area of the rectangle.
We know that,
Area of a rectangle = l × b
Substituting all the values,

Hence, the area of the rectangle is
.
Given that these are all regular, 4 is 173.7. 5 is 98.7. 6 is 90.8.
