Question

A company is designing a new cylindrical water

bottle. The volume of the bottle will be 170 cm³.
The height of the water bottle is 8.1 cm. What is
the radius of the water bottle? Use 3.14 for л.
Height: 8.1 cm

Answer 1

Answer: around 2.6 cm because I rounded to the tenth.

Explanation:

r^2=170/8.1×3.14

r^2=170/25.434

r^2≈6.68

Next square root both sides so r^2 becomes r and 6.68 square rooted is about 2.6 cm is the radius.

R≈2.6cm
