Answer:

$\large\boxed{\sqrt{12}=2\sqrt3\approx3.46}$

Step-by-step explanation:

$\sqrt{12}=\sqrt{4\cdot3}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\=\sqrt4\cdot\sqrt3=2\sqrt3\\\\\text{If you want to get an approximate value, use the calculator:}\\\\\sqrt{12}\approx3.46$

18. Find the measure of each numbered angle.

DiKsa [7]

Answer:

m∠1 = 50°, m∠2 = 90°, m∠3 = 40°, and m∠4 = 50°

Step-by-step explanation:

Angles on straight line are equal;

$m \angle1 + 130 = 180$

$m \angle1= 180 - 130 \\ m \angle1= 50$

Vertical angles are equal,

$m \angle4= m \angle \: 1= 50 \degree$

Complementary angles add up to 90°.

$m \angle3 + m \angle4 = 90 \degree \\ 40 + m \angle3 = 90 \degree. \\ m \angle3 = 90 \degree - 50 \degree \\ m \angle3 = 40 \degree$

Angles on straight line adds up to 180°

$m \angle1 + m \angle2 + m \angle3 = 180 \degree$

$40 + m \angle2 + 50 = 180 \\ m \angle2 = 180 - 50 - 40 = 90$

Tennis balls are sold in cylindrical cans with the balls stacked one on top of the other. A tennis ball has a diameter of 6.7 cm

andrey2020 [161]

Answer:

629.92 $cm^3$

Step-by-step explanation:

The minimum volume of the can that can hold 4 tennis balls must have at least the same volume as 4 tennis balls.

The volume of one tennis ball, V = $\frac{4}{3}\pi r^3$

where r = radius of the tennis ball

The diameter of a ball = 6.7 cm

Its radius will be = 6.7 / 2 = 3.35 cm

Volume, V, will be:

$V = \frac{4}{3}\pi (3.35)^3$

V = 157.48 $cm^3$

Hence, the volume of 4 balls will be:

4 * V = 4 * 157.48 = 629.92 $cm^3$

The minimum volume that the cylindrical can has to have is 629.92 $cm^3$ .
