Answer:

B (V = 4500π ft3; S = 900π ft2)

Step-by-step explanation:

If the great circle's area is 225pi, that makes the radius sqrt225 = 15

The volume of a sphere is (4/3) pi r^3, so the volume would be 3375 * 4/3 pi= 4500pi

The surface area of a sphere is 4 pi r^2, so the Surface area would be 4 * 225 pi = 900pi

That makes the answer B (V = 4500π ft3; S = 900π ft2)

What is 1 2/3 multiple 2/3

Flauer [41]

Answer:

$1\frac{1}{9}$

Step-by-step explanation:

Given the following question:

$1\frac{2}{3} \times\frac{2}{3}$

In order to multiply the two, we have to convert the mixed number into a improper fraction and then multiply the numerator by the numerator, the denominator by the denominator.

$1\frac{2}{3} =3\times1=3+2=\frac{5}{3}$
$\frac{5}{3} \times\frac{2}{3}$
$5\times2=10$
$3\times3=9$
$=\frac{10}{9}$

<u>Convert the improper fraction into a mixed number:</u>

$\frac{10}{9}$
$\frac{10}{9} =10\div9=1\frac{1}{9}$
$=1\frac{1}{9}$

Your answer is "1 1/9."

Hope this helps.
