A wire in the shape of a circle of radius 14 cm is bent in the form of a square, what is the difference of their areas? |
132 cm² 484 cm² 192 cm² 616 cm² |
132 cm² |
Circumference of wire = Perimeter of square 2\(\pi\) x 14 = 4 x (side) 88 = 4 x (side) Side = 22 Difference in their areas = \(\pi\)r² - (Side)² = 616 - 484 = 132 cm² |
