A company is designing a new cylindrical water bottle. The volume of the bottle will be 193 cm cubed 3. The height of the water bottle is 7.2 cm. What is the radius of the water bottle? Use 3.14 for π.

The radius of the cylinder is 2.92 cm

Explanation:

Given:

Volume of cylinder, V = 193 cm³

Height of the cylinder, h = 7.2 cm

Radius of the cylinder, r = ?

We know:

Volume of cylinder = πr²h

On substituting the value we get:

Therefore, the radius of the cylinder is 2.92 cm

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
