What is circumference if diameter is 14 feet
Answers
The circumference is the amount of length around the circle the diameter is the distance across the middle of the circle, first off you need the formulas which are to find the circumference of a circle use the formula C=2 * (pi) * r to find the diameter use the formula D=2 * (pi) and remember that the radius of a circle is the distance from the perimeter of the circle to the center of the circle (half the diameter) so half of 14 equals 7,so in close C= 2 * 3.14 * 7 = 43.96. Enjoy!=)
The circumference of a circle if a diameter is 14 feet is: 43.96
BECAUSE: The formula to solve circumference is: 3.14 (pi) × diameter = circumference
Plug in diameter with 14: 3.14 × 14 = 43.96
Hope this helps!
I need help ASAP!Lainey is sliding down a water slide that is 387 feet long at a rate of 43 feet per second. How long will it take Lainey to travel from the top to the bottom of the slide?
9 seconds
344 seconds
-9 seconds
-344 seconds
Answers
set this up as a proportion. 43 ft/ 1 sec to 387 ft/ x sec. Now cross multiply to get:
43x = 387
now divide by 43 on each side to get:
x = 9 sec

If you do 75/100 you'll get your answer which is 18/25.
It would be 72/100 because percentages are out of 100
