Answer:1.047
Step-by-step explanation:calculate the length of an arc using the formula:
s=θ/360×2×π×r
If the central angle is 20
and a circle has a radius of 3, then the length of the intercepted arc is equal to:
s=20/360×2×π×3
Taking π=3.14:
s=20/360×2×3.14×3≈1.047

Answer:
24416.64 cubic centimeters
Step-by-step explanation:
The equation for the volume of a sphere is . The radius given is 18cm and we are instructed to use 3.14 instead of pi, so our equation will be . Once this is multiplied out, we see that the volume of the sphere is 24416.64 cubic centimeters.
Hope this helps! :)
For the first one the GCF is 4a and the seond one its 2d..
hope this helps
First, convert 1 1/2 into an inproper fraction. To do it you do denominator x whole number plus numerator. This equals to 3/2. Next you do 3/2 x 7 which is 21/2 or 10 1/2. so your answer is 10 1/2 hours
