Ответ:
72 cm²
Step-by-step explanation:
Given the ratio of diameters = a : b , then
ratio of areas = a² : b²
Here the ratio of diameters = 2 : 5 , then
ratio of areas = 2² : 5² = 4 : 25
let x be the area of smaller circle then using proportion
25x = 1800 ( divide by 25 )
x = 72
That is the area of the smaller circle is 72 cm²
