A company is designing a new cylindrical water bottle. The volume of the bottle will be 211 cm^3. The height of the water bottle is 7.9 cm. What is the radius of the water bottle? Use 3.15 for pi

The correct answer is 2.912 cm.

Step-by-step explanation:

A company is designing a new cylindrical water bottle.

Volume of a cylinder is given by π × × h, where h is the height of the cylinder and r is the radius of the cylinder.

The volume of each bottle will be 211 .

The height (h) of the water bottle be 7.9 cm.

Let the radius of the bottle be r cm.

∴ π × × h = 211 ; (π = 3.15)

⇒ × 24.885 = 211

⇒ r = 2.912

The radius of the water bottle is 2.912 cm.

the bolded word " farsighted" could be replaced with visionary.
