The volume of a sphere is 972 pie in cubic inches. what is the radius

Hope that's an apple pie. Just between us, we want to discuss pi, or , or π, not pie.

The formula for the volume of a sphere of radius r is V = (4π/3)*r^3. Since we know that V = 972π, we know that 972π = (4π/3)r^3.

We must solve for r^3, and then solve for r.

To accomplish this, multiply both sides of the equation by 3 / (4π). This results in the equation

(3) 972π

----- * --------- = 729 = r^3.

4π 1

Taking the cube root of both sides of this result, we get r = 9.

The radius of this sphere is 9 units.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
