-- XY is a "diameter" of the circle.
-- A diameter is any straight line inside the circle that goes
through the center and touches the curvy part twice.
-- Every diameter of the same circle has the same length.
-- The distance around every circle is (its diameter) multiplied by (pi).
-- Half of the diameter is called the "radius" of the circle.
A radius is any straight line inside the circle that goes between
the center and the curvy part.
-- The area of every circle is (its radius, squared) times (pi).
-- 'Pi' ( π ) is a number. It's a decimal that keeps going forever
and never ends, so you can never write it exactly with numbers.
-- Pi is roughly 3.14 , and if you use 3.14 whenever you need pi,
then your answers will be about 0.05% too small.
That's very close. When you turn in an answer that's only
0.05% wrong, the teacher knows that you know how to solve
the problem, and that's way more important than the answer.
For the circle in your picture, the diameter is 17in, the radius
is 8.5in, and the area must be (pi) (8.5)² square inches.
You can go ahead and work that out.
Answer:
82 revolutions Step-by-step explanation:
One revolution will be the circumference of the tire, so multiply pi (3.1416) times the diameter (26 in.) to get 81.68 in. then round it up to 82.
Answer is 29 volume I Hope i am right
Answer:
B 35%
Step-by-step explanation:
35/100 reduces to .35. To turn this into a percent, multiply it by 100 and add a percent sign. .35 * 100 = 35. 35%
