total number of student in the data set in the dataset is 90
There are 130 centimeters in 1.3 meters
To solve the problem, we need to get the formula for area of a circle -
Area = pi * r^2; r= radius
= 3.14 * (13cm)^2
= 3.14 * 169cm^2 or 3.14 * 13^2cm^2
= 530.66cm^2
Therefore, the area of the circular plate is 530.66cm^2
If you divid 8.4 x 107 and 3 x 103 you should get 2.8 x 104

Step-by-step explanation:
4 is subtracted from r means the same as r decreased by 4
Subtracted = -
