Answer:
B) 4.52cm²
Step-by-step explanation:
If the shaded area represents 1/4 the area of a circle, then given a diameter of 4.8cm, the area of the entire circle is A=πr²=π(4.8/2)²=π(2.4)²=5.76π=5.76(3.14)=18.0864cm²
Since we're finding 1/4 the area of the circle, then 1/4*18.0864=4.5216cm²
So the shaded area is 4.5216cm², making the closest choice B) 4.52cm²
