Question

circle has a circumference of 132cm. What is the radius of another circle whose radius is 1 1/2 times longer?

Answer 1

Answer:

the radius of another circle whose radius is 1 1/2 times longer  is 115.5cm

Step-by-step explanation:

given that:

circumference of a circle is 132 cm

formula for circumference of a circle is 2πr

so , 2πr = 132 cm

r = (66/π) cm

π can be taken as (22/7)

so r = (66)(7/22) = (3)(7) = 21 cm

radius of the circle = 21 cm

there is another circle whose radius is 11/2 times longer than radius of first circle.

so the radius of another circle is  (11/2)(21) cm

radius of another circle is 115.5 cm
