Find the surface are of a sphere that has a diameter of square root of 29

Hello!

The surface area of a sphere can be found using this equation: SA = 4πr².

The radius is half the diameter. So, half of √29 is √29 / 2, in simple terms.

SA = 4π(√29/2)²

SA = 4π(7.25)

SA = 4(7.25)π

SA = 29π

SA = 91.10618...

Therefore, the surface area of this sphere is 91.11 units².

Without multiplying π, the surface area is 29π units².

If the question asked substitute π for 3.14, the answer is 91.06 units².

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

his chances of getting a coin of higher value is 4/19
