Answer 1

S=4Пr2S=4*3,14*9S приблизительно 113,04

Answer 2

Finding the Area of a Sphere

To find the area of a sphere, we can use the formula:

Area = 4πr^2

where r is the radius of the sphere.

In this case, the radius of the sphere is given as 3 dm (decimeters).

To find the area, we substitute the value of the radius into the formula:

Area = 4π(3 dm)^2

Now, let's calculate the area.

Area = 4π(3^2) Area = 4π(9) Area = 36π

Therefore, the area of the sphere with a radius of 3 dm is 36π square decimeters.

Please note that the value of π (pi) is approximately 3.14159.
