What is the volume of this sphere, rounded to the nearest WHOLE<br> NUMBER?

Alenkinab [10]

Answer:

Step-by-step explanation:

V = (4/3) pi r^3

V = 1.333 * 3.14 * 11^3

11^3 = 1331

V = 1.333 * 3.14 * 1331

V = 5572

12a^5 divided by -4(a^5)^4

Rzqust [24]

Answer:

-3/a^15

Step-by-step explanation:

(12a^5) / -4(a^5)^4

-4(a^5)^4 i am going to simplfy it fist.

-4(a^20)

-4a^20

12 / -4 = -3

a^5/a^20=1/a^15

answer= -3/a^15

X = sin 1/2θ, y = cos 1/2θ, −π ≤ θ ≤ π(a) eliminate the parameter to find a cartesian equation of the curve.

Roman55 [17]

First solve for theta in 'x' equation:
$\theta = 2 sin^{-1} x$

Substitute into 'y' equation:
$y = cos (\frac{2 sin^{-1} x}{2}) = cos (sin^{-1} x)$

Simplify by rewriting cos in terms of sine.
Using pythagorean identity: $sin^2 + cos^2 = 1$

$cos = \sqrt{1-sin^2} \\ \\ y = \sqrt{1-sin^2 (sin^{-1} x)}$
Simplify using inverse function property: $f(f^{-1} (x)) = x$

$y = \sqrt{1 - x^2}$
