The major and minor axes of an ellipse are 25 inches and 4 inches in length. What is the area of the ellipse?

Nostrana [21]

Answer:

Therefore, the area of the ellipse is:

Area = 78.5 inches

Step-by-step explanation:

The formula to find the area of the ellipse is

$\:a\:\times \:b\:\times \:\pi$

The major axis of an ellipse = 25 inches

The minor axis of an ellipse = 4 inches

The value of a = major axis/2 = 25/2 = 12.5 inches

The value of b = minor axis/2 = 4/2 = 2 inches

Thus

The area of the ellipse:

Area = $\:a\:\times \:b\:\times \:\pi$

$=\:12.5\:\times\:2\:\times\:\pi$

$=25\pi$

$=78.5$ inches ∵ $\pi =3.14$

Therefore, the area of the ellipse is:

Area = 78.5 inches

I have a bag with blue marbles and yellow marbles in it. At the moment, the ratio of blue marbles to yellow marbles is 8:5. If I

harina [27]

There were 15 blue marbles in the bag before removing some

Let B=blue marbles and Y= yellow marbles

The ratio of B to Y is

$\frac{B}{Y} =\frac{8}{5}$

If we remove 12 blue marbles and add 12 yellow marbles,

the ratio will be

$\frac{B-12}{Y+21} =\frac{1}{3}$

$3(B-12)=1(Y+21)$

$3B-36=Y+21\\$

$3(\frac{8}{5}Y)-36=Y+21$

$\frac{24}{5}Y-Y=21+36$

$\frac{19}{5}Y=57$

$Y=\frac{57*5}{19}\\$

$Y=15$

$B=\frac{8}{5} (15)\\B=24$

Hence, there were 15 blue marbles in the bag before removing some
