Find the volume of a sphere with a surface area of 3600pi in squared.

Anna71 [15]

Answer:

36000pi

Step-by-step explanation:

V = 4/3*pi*r^3 so we need to know r

we know surface area, which is 4pi*r^2=3600pi. so we can solve for r

r=30

so v = 4/3*pi*30^3 = 36000pi

Which rational number equals 0 point 2 with bar over 2? 1 over 10 1 over 9 2 over 10 2 over 9

Alja [10]

Answer:

$0.\bar2=\frac{2}{9}$

Step-by-step explanation:

We want to find the rational number which is equal to $0.\bar2$ .

Let $y=0.\bar2$ ....eqn(1)

Multiply both sides by 10

$10y=2.\bar2$ .....eqn (2)

Subtract eqn (1) from eqn (2)

$10y-y=2.\bar2-0.\bar2$

$\implies 9y=2$

Divide both sides by 9.

$\implies y=\frac{2}{9}$

11) a - 15 >-40-6 + 3a)<br>

SOVA2 [1]

Answer:

a < $\frac{31}{2}$

Step-by-step explanation:

Given

a - 15 > - 40 - 6 + 3a ← simplify right side

a - 15 > - 46 + 3a ( subtract a from both sides )

- 15 > - 46 + 2a ( add 46 to both sides )

31 > 2a ( divide both sides by 2 )

$\frac{31}{2}$ > a ⇒ a < $\frac{31}{2}$
