Question

Which of the following formulas, when evaluated using rational values for the variables, A will result in an irrational number?
B the formula for the area of a circle
C the formula for the area of a trapezoid
D the formula for the area of a triangle
E the formula for the area of a rectangle

Answer 1

Answer:

The formula for the area of a circle.

Step-by-step explanation:

Formula for area of circle => A = πr².

Formula for area of trapezoid => (Base1+Base2)/2 × Height.

Formula for area of triangle => (Base×Height)/2.

Formula for area of rectangle => Length×Breadth.

So after observing the formula we can see that formula for area of circle contains π which is irrational, so the formula for area of circle will be irrational.

HTH!¡! :)
