We know diameter
and height
.
First find the radius of the bottom of the cylinder,
.
Then find the area of the bottom of cylinder,
.
Then to find volume just multiply the height with the area of the bottom of the cylinder,
.
Hope this helps.
A is the correct answer i think
The experimental probability is computed to be 43/150 or approximately 28.67%. This is computed by dividing the event of number 3 showing by the total number of times the cube is rolled.
The theoretical probability is computed to be 1/6 or approximately 16.67%. Since there is only one side with the number 3, and there is a total of six sides in a cube. Theoretical probability assumes that the number cube is fair and all sides have equal chances of showing up.

Answer: -2w^2 + 25w = 25 or -2w^2 + 25w - 25 = 0</h3>
================================================================
Explanation:
Refer to the diagram below. The width is w. We have two opposite and parallel sides equal to this. The other two parallel congruent sides are L = 25-2w meters long. We start with the total amount of fencing, and then subtract off the two width values, so 25-w-w = 25-2w.
The area of the rectangle is
Area = length*width
Area = L*W
Area = (25-2w)*w
Area = 25w - 2w^2
Area = -2w^2 + 25w
Set this equal to the desired area (25 square meters) to get
-2w^2 + 25w = 25
and we can subtract 25 from both sides to get everything on one side
-2w^2 + 25w - 25 = 0
side note: The two approximate solutions of this equation are w = 1.0961 and w = 11.4039 (use the quadratic formula or a graphing calculator to find this)
Answer:
900π m2
Step-by-step explanation:
surface are of a sphere is 4π(r)^2
now diameter is 30m,so radius will be 15 m
how, 4π(15)^2=900π (m2)
