Question

How would you calculate the area of the quarter circle represented in the upper left hand corner of this figure?

(see pictures for answer options)

Answer 1

Answer:
`(\pi *r^(2) )/(4)`

Step-by-step explanation: We know that the formula for the area of a whole circle is πr². A quarter circle is one-fourth of a circle, so if we divide the area of the whole circle into four, we can find the area of the quarter circle:
`(\pi *r^(2) )/(4)`

Answer 2

Explanation:

To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.
