D is the diameter of the wheel
the circle is π.d = 180
so d = 180/π = 57 cm
Answer:
Option (2)
Step-by-step explanation:
From the picture attached,
When the given shape is rotated about the axis 'a',
Triangle ABC forms a 3-D figure of a cone.
Segment AB is the diameter of the circular base and CD is the height of the cone.
Therefore, Option (2) CONE will be the answer.
It would be 9.54x10^6 because the nine is 6 spaces away from the decimal point if you get what i mean.
-- The two sides of a right <u>angle</u> intersect and make the angle.
So do the sides of any other angle. So they can't be parallel.
-- No two sides of a right <u>triangle</u> ... or any other triangle ...can be parallel.
