Question

Two small circular parks of diameters 16 m and 12 m are to be replaced by a bigger circular park. What would be the radius of the new park if the new park occupies the same space as the two small parks?​

Answer 1

Answer:

correct and is :10 m

Step-by-step explanation:

Let R denotes the radius (in m) of the new bigger circular park.

Hence from above data we get as follows,

π*R^2 = π*(16/2)^2 + π*(12/2)^2

or R^2 = 64 + 36 = 100 or R = 10 (m)
