The answer is 40
1.6/40=.04
The area of a circle is equal to Pi x Radius squared. Or Pi (the symbol) r (then to the second power.) The radius is half of the entire circle (the diameter.)
If y=f(x)
Domains are input or plug in value of x which we put in equation for a variable accordingly we get output or y's values which is called range.
Here in the fig. clearly shown g(4)=5
Anwser is B.
Total number is 24.
Let the number of dogs be 3x and the number of cats be x.
3x + x = 24
4x = 24
x = 24/4
Number of dogs is : 24/4 × 3
Thus the answer is B.
Hope it helped!!
