How many radius make a complete circle​

Mathematics
1 answer:
user100 [1]3 years ago
4 0

Answer:

Step-by-step explanation:

It takes 2 π 2\pi 2π radians (a little more than 6 radians) to make a complete turn about the center of a circle. This makes sense, because the full circumference of a circle is 2 π r 2\pi r 2πr , or 2 π 2\pi 2π radius lengths.

Use the following problem to answer questions 7 and 8. Carrie draws 5 cards simultaneously from a well-shuffled deck of 52 playi
Alexxx [7]

Answer:

The probability that she chooses 3 spades and 2 cards that are not spades is

0.08154

Step-by-step explanation:

52 deck cards have 13 spades , 13 clubs , 13 diamond, 13 hearts

spades = 13

Non spades = 39

Selecting 3 spades = 13C3 (Using combination)

selecting 2 spades = 39C2

in total 5 cards are drawn = 52C5

Probability of drawing 5 cards (3spades+2 non spades)

                               =\frac{ 13C3*39C2}{52C5} = 0.08154
