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.

answer: the equation matches the regression

step-by-step explanation:

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
