The diameter of the pizza shown is 35 millimeters. Which measurement is closest to the area of the pizza in square millimeters?
A. 54.95 mm2
B. 109.9 mm2
C. 781.751 mm2
D. 961.625 mm2
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is given, we first need to divide that by 2 to get the radius.
Radius = 35 mm / 2 = 17.5 mm
Now plug the radius into the formula:
A = π(17.5)^2
A ≈ 3.14 x 306.25
A ≈ 960.625 mm2
The measurement closest to the area of the pizza in square millimeters is:
D. 961.625 mm2
