Area = πr^2
Circumference = 2πr
Blue:
Area = 5^2 = 25π
Circumference = 2 * 5 * π = 10π
Pink:
Area = 6^2 = 36π
Circumference = 2 *6*π = 12π
White:
r = 3
Area = 3^2 = 9π
Circumference = 2 *3 = 6π
Red:
Area = 7^2 = 49π
Circumference = 2 *7 = 14π
Answer:
Step-by-step explanation:
there are a total of 20 marbles and the chance that it is blue is 8/20 so multy that by itself and the answer is 4/25
Answer:
