Answer:
339.336 m^2
Step-by-step explanation:
Given data
Radius= 6meters
We know that the surface area of a half-sphere is given as
A=3πr^2
A= 3*3.142*6^2
A= 3*3.142*36
A=339.336 m^2
The range of values of a random variable
Given that there are 10 children who own a dog, and 14 children who do not, the ratio of the children that owns a dog to the children that do not own a dog, is 10:14.
To express the ratio in a simplify fraction, we will just use fractional notation. Thus, it is simply 10/14, or 5/7 as its simplest form.
