Step-by-step explanation:
step 1. pythagorean theorem is a^2 + b^2 = c^2 where a, b are the legs and c is the hypotenuse
step 2. 4^2 + 5^2 = c^2
the answer is 153.86 ft squared
= the formula for the area of a circle is A=πr2
= area = pi x radius squared
= the radius is 7 feet, square that to get 49
= multiply 49 by pi to get the area: 153.86 square feet
153.86 ft squared
1. in picture 1
2. in picture 2
Hope this helps :T
Also I am not so shure about 2, but I am 98% shure 1 is right.
X=2/3y because you want to know what roberts time is
To determine the probability that there will be no women, you need to find the probability of women and subtract it from the total
60 - 10 = 50
so you find the probability with the total number of people being 50, that way the women's probability is eliminated.
5 out of 50 multiplied by the original total of the people, 60
(5÷50)×60 = 6
Therefore the probability of randomly choosing 5 people, excluding women is 6
