Step-by-step explanation:
- N% of 40=10
N/100×40=10
N=10×100/40=25

False. In a coin, there are 2 possible out comes i.e. a head and a tail. if p is the probability of one side coming up, then the probability of the other side comin up will be q = 1 - p.
Therefore, if the probability of head coming up is 3/10, the probability of tail coming up will be 1 - 3/10 = 7/10.
Answer:
She could divide 9.42 by Pi to find the radius, then multiply 9.42 by the radius.
(Last option)
Step-by-step explanation:
We need the formula for the area of a circle:
A = πr²
Remember r² = r × r
So you could rewrite the formula like this:
A = π × r × r
If π × r = 9.42, then the area becomes:
A = 9.42 × r
"<em>Then multiply 9.42 by the radius</em>".
To find "r", divide 9.42 by π.
π × r = 9.42
r = 9.42/π
"<em>Divide 9.42 by Pi to find the radius</em>".
