If E partitions CD by a ratio of 1/8, then which of the following could be the location of E?

Answers

You neglected to copy the choices that are given along with the
question, so It's hard for us to steer you toward the correct one.
But take heart ... all is not lost ! As hard as you might try to keep
us from discovering the correct answer, the people who answer
questions on this website are so good that we can often determine
the correct answer without even seeing the choices !

If 'E' partitions 'CD' in the ratio of 1/8 , then 'E' must be located exactly
one ninth of the distance from 'C' to 'D'. Then the piece on one side
of 'E' is 1/9 of the total distance, and the piece on the other side of it
is the other 8/9 of the total distance. The ratio of the pieces is then

(1/9) / (8/9) = 1/8 .

Find the area of a circle with a diameter of 22 inches?

Answers

$R=(Diameter)/(2)$

then

$R=(22~in)/(2)$

$\boxed{R=11~in}$

now we just need to apply this formula

$S=\pi*R^2$

$S=\pi*11^2$

$\boxed{\boxed{S=121*\pi~in^2}}$

$d=2r\n d=22\n 2r=22\n r=11\ inches\n \n A=\pi r^2\n A=\pi \cdot 11^2=3,14 \cdot 121=379,94\ inch^2$
