Question

Find the diameter of a circle whose circumference is equal to the sum of the circumference of the two circles of diameters 36m and 20m

Answer 1

Answer:

56m

Step-by-step explanation:

circumference of required circle = 2πr = πd

(diameter = 2r)

circumference of 1st circle

= 2 × π × 18

= 36π

circumference of 2nd circle

= 2 × π × 10

= 20π

sum of the circumference of two circle

= 36π + 20π

= 56π

circumference of required circle = πd = π56

d = 56

diameter of the required circle is 56m
