Answer:

r = \sqrt{\frac{A}{\pi } }

r = 17.2 cm

Step-by-step explanation:

∵ The area of the circle A = πr²

∴ r² = A/π

∴ r = √(A/π)

∵ A = 54 cm²

∵ π = 22/7

∴ r = √(54/(22/7)) = √(54×7/22) = 17.2 cm

barxatty [35]

Answer:

155 Units

Step-by-step explanation:

Rate of Bug (given) = 11 units PER MINUTE

It never changed direction, so it was going in positive direction (assume).

In 7:15 pm (evening), it was at Point 100,

We want the point at which it was at 7:20 pm.

7:20pm - 7:15pm = 5 minutes

So, time passed 5 minutes. It's rate is 11 units PER MINUTE, so in 5 mins:

11 * 5 = 55 units

Assuming he is going in positive direction, the bug will be at:

100 + 55 = 155 Units

Please help me with this question. I don’t understand how to do this.
Blizzard [7]

Answer:

133/152

Step-by-step explanation:

The probability of 2 independent events is the product of the individual events.  Independent means the first event has no effect on the probability of the second event.  Since we are replacing the first marble, the first even has no effect on the probability of the second event.  

There are 48 total marbles

Let A = pulling a blue marble

Let B = pulling a red marble

So

P(A) = 14/48

P(B) = 19/48

and

P(A then B) = (14/48)(19/48) = 266/2,304 = 133/1,152
