One formula for finding the length of the arc is:

$s=r\theta$

where s is the length of the arc, r is the radius of the circle, and $\theta$ is the measure of the central angle in radians. So, in this case, we have:

$s=(7)(2)=14$

The arc measures 14 units.

Answer:

d ≤ - 7

Step-by-step explanation:

Given

- 38d - 57 ≥ - 19d + 76 ( add 19d to both sides )

- 19d - 57 ≥ 76 ( add 57 to both sides )

- 19d ≥ 133

Divide both sides by - 19, reversing the symbol as a result of dividing by a negative quantity.

d ≤ - 7

Find the volume of this sphere. Use 3 for TT. V [?]in3 V = Tr3 8 in

frutty [35]

Answer:

The volume of the sphere is 2048 in³.

Step-by-step explanation:

The volume of a sphere is given by:

$V = \frac{4}{3}\pi r^{3}$

Where:

r: is the radius = 8 in

Having the radius and by using 3 for π, the volume is:

$V = \frac{4}{3}*3 (8 in)^{3} = 2048 in^{3}$

Therefore, the volume of the sphere is 2048 in³.

I hope it helps you!
