Answer:
The approximate length of the radius, r is 12 inch.
Step-by-step explanation:
Given:
A circle P is given having circumference C,
C = 75 inch
pi = π = 3.14
radius = r
To Find:
radius = r = ?
Solution:
Circumference:
In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is the (linear) distance around it.
That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.
Formula is given as

Substituting the values we get
75 = 2 × 3.14 × r
∴ 
We approximate radius to
radius = 12 inich
Scott would make double of the original amount
Answer: 
Step-by-step explanation:
Given: Number of cards in a standard deck = 52
If we already chosen a diamond card, then the number of cards left in the deck =52-1=51
The number of spades remains same = 13
Now, the probability that you choose a spade, given that you have already chosen a diamond is given by :-

Hence, the the probability that you choose a spade, given that you have already chosen a diamond
