A shere has a diameter of 24 units what is it’s volume in cubic units
Vika [28.1K]

Answer:

7238 rounded to the nearest whole number.

Step-by-step explanation:

To find the volume of the sphere, we use the formula.

v =  \frac{4}{3} \pi  {r}^{3}

The radius will be 24 units ÷ 2 = 12 units.

Hence, the volume is

\frac{4}{3} \pi \times  {12}^{3}

When entered in a calculator you'll get a result of 7238.23 cubic units in or 7238 rounded to the nearest whole number.

After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6, 3), B'(-2, 1),
Rasek [7]

Answer:

<em>A</em>(-3, 6), <em>B</em>(-1, -2), <em>C</em>(-7, 1)

Step-by-step explanation:

To the pre-image after a 270°-counterclockwise rotation [90°-clockwise rotation], just reverse it by doing a 270°-clockwise rotation [90°-counterclockwise rotation]:

Extended Rotation Rules

  • 270°-clockwise rotation [90°-counterclockwise rotation] >> (x, y) → (-y, x)
  • 270°-counterclockwise rotation [90°-clockwise rotation] >> (x, y) → (y, -x)
  • 180°-rotation >> (x, y) → (-x, -y)

So, perform your rotation:

270°-clockwise rotation [90°-counterclockwise rotation] → <em>C</em><em>'</em>[1, 7] was originally at <em>C</em>[-7, 1]

→ <em>B'</em>[-2, 1] was originally at <em>B</em>[-1, -2]

→ <em>A</em><em>'</em>[6, 3] was originally at <em>A</em>[-3, 6]

I am joyous to assist you anytime.
