Answer:
d=8.0 meters
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h
We are given the volume and the height
117.23 and the height 7
117.23 = 1/3 *3.14 *r^2 * 7
117.23 = 7.3266666666 *r^2
Divide each side by 7.3266666666
117.23/7.3266666666 = 7.3266666666 *r^2/7.3266666666
16.00045496 = r^2
Take the square root of each side
sqrt(16.00045496) =sqrt( r^2)
4.000 = r
We found the radius but it wants the diameter
d = 2*r
d =2*4.0
d=8.0 meters

Answer:
<h2>The segment FE is a tangent of the sphere.</h2>
Step-by-step explanation:
Obseve the sphere in the image attached.
Notice that point A is the center of the sphere. GD is the diameter, which means AG and AD are radius.
On the other hand, remember that a tangent is a line that intersects the figure at only one point, otherwise, it would be a secant.
Therefore, segment BC is a secant and segment FE is tangent.
So, the right answer is segment FE.
2-1, 3-2, 4-3, 1*1, 1/7, any number of expressions fit the bill here.
Answer:
The total cost of the petrol is 2.075 cents.
Step-by-step explanation:
The cost of per gallon petrol = 0.83
Drive per gallon = 8 miles
Here, total distance traveled = 20 miles.
So, the total petrol used for 20 miles = (20 / 8) gallons
= 2.5 gallons
Now, cost of petrol per gallon = 0.83 cents
So, total cost of petrol = 0.83 x 2.5 = 2.075 cents
Hence, the total cost of the petrol is 2.075 cents.
