500=4πr^2. first divide 500 from four which will equal 125, then divide 125 with π and it will equal 39.788 . finally √39.788. the answer will be r=6.3 or 6
Answer:
circle(50)
Step-by-step explanation:
The circle should have a diameter of 50 so the answer is simply "circle (50)"
24 because when you plug in 0 for both x and y:
0=12(0)+24
12*0=0, leaving you with 24.
Answer:

Step-by-step explanation:
We have been given that a series of 3 separate, adjacent tunnels is constructed through a mountain. Its length is approximately 25 kilometers.
Each of the three tunnels is shaped like a half-cylinder with a radius of 5 meters.
Since we know that volume of a semicircular or a half cylinder is half the volume of a circular cylinder.
, where,
r = Radius of cylinder,
h = height of the cylinder.
Upon substituting our given values in volume formula we will get,






Therefore, the volume of earth removed to build the three tunnels is
.
The answer would be 9 Permutation 3 (or 9P3) which is equal to 504 possible ways.
