Not enough information???
Ok so,,,, first you find the area of a trapezoid which is b1 plus b2 times h over 2 so it is 9 plus 7 times 6 divided by two then you get 48 and you subtract by 20 times 24 bc its the area of rectangle so 480 minus 48 which is 432 cm squared
The complete question is
Three tennis balls are stored in a cylindrical container with a height of 8 inches and a radius of 1.43 inches. The circumference of a tennis ball is 8 inches. a) Find the volume of a tennis ball b) There are 3 tennis ball in the container Find the amount of space within the cylinder not taken up by the tennis balls. Round your answers to the nearest hundredth.
Part a)
we know that
length of a circumference=2*pi*r----------> r=length/(2*pi)---> 8/(2*pi)
r=1.27 in------> radius of tennis ball
volume of a tennis ball is equals to the volume of a sphere
[volume of a sphere]=(4/3)*pi*r³----> (4/3)*pi*1.27³---> 8.58 in³
the answer Part a) is
the volume of a tennis ball is 8.58 in³
Part b)
[volume of the container]=pi*r²*h-----> pi*1.43²*8----> 51.39 in³
[volume of 3 tennis balls]=8.58*3-----> 25.74 in³
the amount of space within the cylinder not taken up by the tennis balls is
51.39-25.74-----> 25.65 in³
the answer Part b) is
25.65 in³
Answer: 0.79 or 79%
Step-by-step explanation:
Given : The probability that the athletes are football players : P(A)=0.33
The probability that the athletes are basketball players: P(B)=0.66
The probability that the athletes play both football and basketball : P(A∩B)=0.20
Now, the probability that the athlete is either a football player or a basketball player is given by :-
Hence, the probability that the athlete is either a football player or a basketball player = 0.79
Or we can write it as 79%.
