The ratio of growth is 26.1/25.9 = 261/259
in x years the median age = 25.9 * (261/259)^x
in 2019 (after 10 years) = 25.9 * (261/259)^10 = 27.97
Given:
Diameter of ball = 8 cm
To find:
The volume of the ball.
Solution:
We know that the radius of sphere is half of is diameter.
It is given that the the diameter of ball is 8 cm. So, the radius of the ball is:
The radius of the ball is 4 cm.
The volume of a sphere is:
Where r is the radius of the sphere.
Putting in the above formula, we get
Therefore, the volume of the ball is about 267.95.
Answer:
The awnser would be 9 because its under the sum of 10
No it is not valid because you only asked 50 students not every student so it could not be 40%.
Answer:
Step-by-step explanation:
hypotenuse (h) = 8
base(b) = 2
cos A = b / h
cos A = 2 / 8
cos A = 1/ 4
A = Cos^-1 ( 1/4)
A = 75.52 °
