Question

The radius of one circular field is 20m and that of another field is 48m.Find the radius of the third circular field whose area is equal to the sum of the areas of the two fields.

Answer 1

Answer:

the answer is 52 m lets see how it is

Step-by-step explanation:

first circular field:

radius = 20m

then area = π *20^2

second circular field:

radius = 48m

then area = π *48^2

now third circular field: let radius = R

area = π20^2+π48^2

πR^2 = π(400+ 2304)

R^2 = 2704

R = √52*√52

R = 52.
