Question

Q. 15. What happens to the volume of a sphere if its radius is doubled?
Q. 16. Write the probability of a sure event.
​

Answer 1

Answer:

ans (15) Then the radius of sphere is doubled then volume become eight times.

Step-by-step explanation:

ans(16) The probability of a sure event is 1. ... For example ,it's a sure event to obtain a number between 1 and 6 when rolling an ordinary die. The probability of a sure event has the value of 1. The probability of an impossible event has the value of 0.

here is your answer

hope it's help :)

Answer 2

Answer:

15.Volume of sphere = 4/3 πr^3

If radius is doubled

Then, Volume if sphere = 4/3 π (2r) ^3

= 4/3 π (8r^3)

= 8 { 4/3πr^3}

Hence, volume will become 8 times

16.Probability of a sure event is 1.
