Answer:

The radius of the cylinder is $r=6$ meters.

Step-by-step explanation:

To determine:

What is radius?

Information Fetching and Solution Steps:

The volume of the cylinder = 1,921.68 cubic meters

$\pi \approx 3.14$

The height = 17 m

As the formula of the volume of the cylinder

$V=\:\pi \:r^{2} \:h$

The radius can be determine as

$r^{2} \:=\:\frac{V}{\pi \:h}$

$r=\sqrt{\frac{V}{\pi \:\:h}}$

$\:r=\sqrt{\frac{1921.68}{\left(3.14\right)\:\left(17\right)}}$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$r=\sqrt{\frac{1921.68}{3.14\cdot \:17}}$

$\mathrm{Multiply\:the\:numbers:}\:3.14\cdot \:17=53.38$

$r=6$ meters

Therefore, the radius of the cylinder is $r=6$ meters.

Which THREE sets of angles can be used to construct triangles? A) 50°, 65°, 65° B) 45°, 50°, 85° C) 20°, 60°, 100° D) 30°, 60°,

Answer:

A) 50°, 65°, 65°

B) 45°, 50°, 85°

C) 20°, 60°, 100°

Step-by-step explanation:

To see if the angles can be used to construct triangles, you have to check if the degrees add up to 180 (Since the degrees in a triangle always have to add up to 180 degrees).

A) 50° + 65° + 65° = 180° (Good!)

B) 45° + 50° + 85° = 180° (Good!)

C) 20° + 60° + 100° = 180° (Good!)

D) 30° + 60° + 70° = 160° (Bad!)

E) 20° + 45° + 120° = 185° (Bad!)
