Answer:
Radius = 75 inches .
Step-by-step explanation:
Given : A circle has a central angle measuring 90° that intersects an arc of length 117.75 inches.
To find : what is the length of the radius of the circle.
Solution : We have given
Central angle = 90°
Arc of length = 117.75 inches.
Arc length = .
Plug the values
Theta = 90 , pi = 3.14 , arc length = 117.75 .
117 .75 = .
117 .75 =
On multiplying both sides 4
117.75 * 4 = 2 * 3.14 * radius .
471 = 6 .28 * radius .
On dividing both sides by 6.28
radius = .
Radius = 75 inches .
Therefore, Radius = 75 inches .

Step-by-step explanation:
Since Gloria cannot pay for each minute talked but for packages of 200 minutes at the rate of $25 each, we have to make calculations according to these conditions as follows:
Month 1:
Gloria talked on her cell phone for . So, she had to buy 2 packages of
for
each package.
Hence:
Month 2:
Gloria talked on her cell phone for . So, she had to buy again 2 packages of
for
each package.
Hence:
Month 3:
Gloria talked on her cell phone for . So, she had to buy 3 packages of
for
each package.
Hence:
Then, if we take the total Gloria had to pay for the frist three months, we have:
