Circunference=pi times diameter
diameter=16in
circunfernce=16pi in
that is exact because pi is irrational
if we were to aprox pi to 3.14 hen
16 times 3.14=50.24
so answer is 16pi or 50.24 in
Answer:
te answer is 1812
Step-by-step explanation:
you just end up multiplying it by 2
Higher standard deviation shows a greater spread of the data.
2005 - sd=3.5
2006 - sd=2.8
2007 - sd=1.0
2008 - sd=4.0
The correct statement is the last statement which says the game scores of season 2005 have a greater spread than the game scores of season 2006
-- 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.
