A. The wire needs to be 138.226 cm long but already 34.5565 cm of the circle has been covered.
B. To determine the length of the wire needed, we subtract a quarter of the circles circumference from its whole circumference.
Step-by-step explanation:
Step 1:
The circumference of a circle is obtained by multiplying the radius with 2π.
The circumference of a circle
Here the radius of the circle is 22 cm but already a quarter of the circumference has been covered with wire.
Step 2:
So to determine the length of the wire needed, we subtract a quarter of the circles circumference from its whole circumference.
So the circumference of the circle cm.
cm and
cm.
So the wire needs to be 138.226 cm long but already 34.5565 cm of the circle has been covered. An additional 103.6695 cm of wire is needed to cover the remaining circle.
Answer:
Option (D) is correct.
No, They will not intersect.
Step-by-step explanation:
Given Points for g(x), (1,2) , (2,4) and (3,6)
Since g is a linear function then it must be in form of g(x) = mx +c where, c is constant and m is slope.
We first calculate the slope using,
Here, consider
Substitute above, we get slope as,
Thus, equation becomes g(x) = 2x + c ...(1)
For c plug the values in (1),
(1,2) ⇒ 2= 2 + c ⇒ c = 0
Thus, Equation of G(x) is 2x.
When we plot it it do not intersect f(x).
Thus, Option (D) is correct.
No, They will not intersect.
