Answer:
15 cm
Step-by-step explanation:
Circumference of circle= 2πr, where r us the radius of the circle.
Given that the circumference of circle is 60πcm,
60π= 2πr
Divide by 2 on both sides,
15π= πr
Divide by π on both sides,
15= r
Thus, radius of circle= 15cm.
Answer:
yes
Step-by-step explanation:
Answer:
6/25
Step-by-step explanation:
P(gray) = 2/5
P(blue) = 3/5
P(1st gray & 2nd blue) = (2/5)*(3/5) = 6/25
As the question already indicated the sequence, so no combination (nCr) should be considered.
You would use the formula v=a^2 h over 3
