Area of circle=pi x radius ^2, if the line through the center of the circle goes from one end to the other, it is the diameter, so you need to divide it by 2 before you put it into the formula. If the line is only half way, then it is already the radius, so use that number in the formula.
2. the line is half way only, so it is the radius=21. You can use it in the formula:
a=3.14 x 21 ^2
a=3.14x441
a =1384.74
3. the line goes all the way to the other side of the circle, so it is the diameter=56. you need to divide it by 2 to get the radius: so 56/2=28=radius. Now us 28 in the formula:
3.14 x 28^2
a=3.14 x 784
a=2461.76.
just continue doing that for the rest of the problems. Hope this helps.
Answer:
9/14
Step-by-step explanation:
You multiply the two fractions. So 5/7*9/10, you just multiply across. This would give you 45/70. Then, after simplifying, this fraction is 9/14. So, Sean ran 9/14 of a mile on Sunday. Hope this helps, Sorry if im wrong!!
A dilation is basically a factor of enlargement or reduction, where you multiply the factor for the dilation.
So,
Multiply the numerator 5 by the factor of 8.
5*8= 40
40/8 ft^2= 5 ft^2
The new area if 5 ft^2.
I hope this helps!

Answer: 0.1008188
Step-by-step explanation:
The question will usng the poisson distribution formula:
Given :
Mean(λ) number of occurrence in a given interval = 3
P(X=x) = Probability of exactly x occurrence in a given interval
Number of desired occurence(x) = 5
P(X=x) = [(λ^x) * (e^-λ)] / x!
Where ; e = base of natural logarithm = 2.7182818
P(X=5) = [(3^5) * (e^-3)] / 5!
P(X=5) = [(243) * (0.0497870)] / 120
P(X=5) = [12.098257] / 120
P(X=5) = 0.1008188
