Answer:15252.25π^3
Step-by-step explanation:
Radius=r
Circumference=247 ud
Circumference=2 x π x r
247=2πr
Divide both sides by 2π
247/2π=2πr/2π
123.5π=r
Radius=123.5π
Area of circle=π x r x r
Area of circle=π x 123.5π x 123.5π
Area of circle=15252.25π^3
Answer:
24 hours
Step-by-step explanation:
Kristen = 8 hours
Kristen and Courtney = 6 hours
Courtney = x hours
in six hours kirsten can do 6/8 of the job
6/8 = 3/4
So kirsten is going to be doing 3/4 of the job
Courtney is only going to do 1/4 of the job
Number of hours it takes Courtney to do the job
6/x = 1/4
Cross product
6 * 4 = x * 1
24 = x
x = 24 hours
It will take Courtney 24 hours to type a 50-page paper on her own
