Answer:
The volume of tennis ball = 38.808 .
Volume of golf ball = 33.523 .
Step-by-step explanation:
Given: The radius of the tennis ball is 2.1cm and the radius of thr golf ball is 2.0cm. the formula is V=4πr(to the 3rd power) /3 .
To find: Volume of tennis ball and golf ball .
Formula used: Volume = .
pi(π) = .
Explanation : We are given that
Radius of the tennis ball = 2.1 cm
radius of the golf ball =2.0 cm.
We need to find the volume of each ball
So , plugging the given values of radius in above formula
Volume of the tennis =
On simplification we get, volume of tennis ball = 38.808
Volume of the golf ball=
On simplification we get, volume of golf ball = 33.523
Therefore , The volume of tennis ball = 38.808 .
Volume of golf ball = 33.523 .
Answer:
The perimeter of a parallelogram is 42 cm.
Step-by-step explanation:
The area of a parallelogram is 72 cm².
The formula for area of a parallelogram is
It is given that the distances between the point of intersection of the diagonals and the sides are 3 cm and 4 cm.
The distance between point of intersection of the diagonals and the opposite sides are same.
The measure of a side is 12 cm.
The measure of another side is 9 cm.
The perimeter of a parallelogram is
Therefore the perimeter of a parallelogram is 42 cm.
