The diameter of a circle is 10 cm. Find its area in terms of π.
2 answers:
Answer:
A = 25
or A = 78.54
Step-by-step explanation:
The diameter of a circle is just the radius two times, in this case, the diameter is 10. This means that the radius would be 5. Therefore we can use 5 as our r variable in the formula for area (A=),
A = , simplify
:
A = 25
From here you can leave the asnwer in its excat form, 25, or you can simplify it by multiply 25 times pi to get 78.54 (rounded to the hundreths place).

To draw a heart, one would be choosing 1 card of 13 possible hearts, and 0 from the remaining 39 non-hearts. With respect to the entire deck, one would be choosing 1 card from 52 total cards. So the probability of drawing a heart is
When Michelle replaces the card, the deck returns the normal, so the probability of drawing any card from a given suit is the same,
. In other words, drawing a spade is independent of having drawn the heart first.
So the probability of drawing a heart, replacing it, then drawing a spade is
