Answer:
first use the Pythagoras theorem to find for a,b and c
that is. c²= b²+a²
then when you find the answers find the area of A,B and C
that is <u>1</u>× base × height
2
1121/31 or you can make it a whole number
The variation equation is p = kr^2
<h3>How to determine the variation equation?</h3>
The variables are give as:
Pressure = P
Radius= r
The direct variation from p to the square of r is represented as:

Express as an equation
p = kr^2
Where k represents the constant of variation
Hence, the variation equation is p = kr^2
