Answer:
All Circles we get by horizontal cross section are not equal.
Step-by-step explanation:
Given: A cone.
To find: Shape of Horizontal cross section of cone are all congruent or not.
Two shapes are congruent if they are equal in measure or if they overlap each other completely.
Shape of horizontal cross section of cone is CIRCLE.
Two Circles are congruent if they have same radii.
Cross section 1: Horizontal cross section of cone near the base is a large circle almost equal to radius of cone.
Cross section 2: Horizontal cross section of cone near the top is a smallest circle whose radius is almost equal to 'zero'.
Cross section 3: Horizontal Cross section of cone in middle is a circle whose radius is between top's circle and base circle.
Its clear from above that these three cross sections are not congruent as circle don't have same radii.
Therefore, All Circles we get by horizontal cross section are not equal.
Answer: 15 inches is the height of Keisha's fish tank.
Step-by-step explanation: Basically, multiply your length x width, which is 12 x 10. 12 x 10 = 120.
Next, divide 1800 by 120.
1800 divided by 120 is 15.
So, 15 inches is the height of the fish tank.
the answer is MO.
i know because its longer than the others.
Answer:
C
Step-by-step explanation:
The answer is C, 12 and 13, because the exact square root of 156 is about 12.5. On a number line, 12.5 is in between 12 and 13. Hope this helps, good luck, and God bless!
