Hey user!!!
given the radius of the cylindrical mold is 2 inches and height is 3 inches.
volume of the cylindrical mold = πr²h
= 3.14 × 2 × 2 × 3
= 37.68 in³
radius of the spherical mold is given = 2 inches
volume of the spherical mold = 4/3πr³
= 4/3 × 3.14 × 2 × 2 × 2
= 100.48/3 in³
difference between the amount of wax needed = 37.68/1 - 100.48/3
= ( 113.04 - 100.48 ) / 3
= 12.56/3
= 4.186...
so approximately 4.19 in³
hence, correct option is 4.19 in³
cheers!!!
Answer: Mr. Parker can expect the trip to be at least 3 and a half hours
1 tennis racquet and 5 cans of tennis balls
at least 4 days
Step-by-step explanation:
300 - 55 = 245
3.25 x 5 = 16.25 43.75 + 16.25 = 60
40 / 12 = 3.3333333 So you can only visit 3 days with the daily pass before it cost 40 dollars
Kian has to work with 6 square inches
Step-by-step explanation:
Given that the logo has to be created in a rectangular shape
Length = 3 inches
Width = 2 inches
We have to calculate the area of the given space to find out that how much area Kian will work with.
So,
Hence,
Kian has to work with 6 square inches

Answer:
Answer is 25ft.
Step-by-step explanation:
l=20ft.
h=16ft.
let 'w' be x.
then
l=√w2+h2
or l=√x2+(16)2
squareing on both side.
or (20)2=√(x+16)2
or 400=x+16
or x=400/16
or x=25.
so that the value of W is 25ft.
Answer:
D) We are 95 percent confident that the mean difference in scores for all children in the program is between 20.1 points and 23.9 points.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95 percent confidence interval (20.1,23.9)
We are 95% sure that the population mean(that is, the mean for all children in the program) is in this interval. So the correct answer is given by option D.
