this circle has a diameter of 5 inches which of these measurements is closest to the circumference of the circle 15.7 7.85 31.4
1 answer:
Answer:
The closest measurement is 15.7
Step-by-step explanation:
The formula for circumference is
The diameter is double the radius, so to get the radius we divide by 2.
5 divided by 2 is 2.5
Knowing "r" is 2.5 we can plug that into our equation and solve.
2 · · 2.5 ≈ 15.71
The closest measurement is 15.7

There we have an information of two functions
Using this two functions , we need to find the composition of functions (h\circ g)(t).
The composition of two functions h and g is the new function , by performing g first and then performing h.
Composition of h and g (t) =
First plugin the value of
We know that , we need to find h(3t+3),
That is, to replace t by 3t+3,
Now distribute 2 into 3t+3,
Now plug in
Thus the solution is (D).
