The perimeter of angle abc is 98 centimeters. if the radius circle a is twice the radius of circle c and the radius of circle b is four times the radius of circle c, then find the radius of circle c.

Answer : The radius of circle C is 7 cm.

Explanation:

As we shown in the figure below:

Let the radius of circle C is x

Let the radius of circle A is 2x

Let the radius of circle of B is 4x

So The length of side AC of ΔABC is x+2x = 3x

The length of side  BC  of ΔABC is 4x+x = 5x

The length of side AB of ΔABC  is 4x+2x = 6x

Since we have given that the perimeter of triangle ΔABC is 98 cm.

and we know that the perimeter means the sum of boundary of sides of triangle .

so, Perimeter = 6x+5x+3x = 98 cm

⇒ 14x= 98

⇒ x=

⇒ x=7

So, the radius of circle C is 7 cm.

Blue: 2/8

Red or Yellow: 3/8

Not Brown: 8/8

Not Green: 5/8

Number Five: 20%

Step-by-step explanation:

First Four Questions: See how many parts the spinner is in then count the number of colors its asking or not asking for and put that number over the total amount of parts

Question Five: If it shows up on time 80 percent of the time then the other 20 percent of the time they were late so there is a 20 percent chance of that happening again.
