Question
The figure above shows a quarter circle of radius 28 cm.
Find the area of the figure. (Take ? = )
Solution
Unfortunately, the question seems to be incomplete. The value of pi (?) is not provided. However, if we assume the standard value of pi (approximately 3.14), we can calculate the area of the quarter circle.
The area of a full circle is given by the formula πr², where r is the radius of the circle.
Step 1: Substitute the given radius into the formula. In this case, r = 28 cm. So, the area of the full circle is π(28 cm)² = 2464π cm².
Step 2: Since the figure is a quarter of a circle, its area is 1/4 of the area of the full circle. So, the area of the figure is 1/4 * 2464π cm² = 616π cm².
So, the area of the figure is 616π cm², or approximately 1936.5 cm² if we use 3.14 as the value of π.
