Answer:
18
Step-by-step explanation:
Alright so here you have to work backwards. the volume of a cylinder is pi*r^2*h.
Your equation: 486 pi = pi*r^2*6
You know the height is 6 feet, so you can get rid of the 6 feet hanging off of your equation by dividing both sides by 6:
81 pi = pi*r^2
Now you notice that both sides have pi. You can eliminate it by dividing both sides by pi:
81 = r^2
To isolate the r, radius, you have to take the square root of both sides, since a square root is the inverse operation of squaring. You get:
9 = r
Now that you have the radius, you can find the diameter by multiplying the radius by 2, because a diameter = 2 * the radius:
18 = d
Hope this helps!
HGI is congruent to JIG due to the Side-Side-Side congruence theorem.
This theorem states that if the three sides of one triangle are congruent to the three sides of another triangle, the triangles must be congruent.
In order to create these triangles, we must draw a diagonal in this triangle. This will be a shared side between both triangles.
A rectangle's opposite sides are congruent; this means the top and left sides, which are part of one triangle, will be congruent to the bottom and right sides, which are part of the other triangle.
This gives us all 3 sides of both triangles congruent, and therefore the congruence theorem applies.
No because if you convert them into a percentage, you get 11/15 as 73.3% and 1/2 is 50%. Hope this helps
