A company is designing a new cylindrical water bottle. The volume of the bottle will be 189 cm cubed. The height of the water bottle is 7.3 cm. What is the radius of the water bottle? Use 3.14 for pi.

The radius is 2.9cm

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cylinder

We know that the volume of a cylinder is given as

V= πr²h

Given data

Volume V= 189cm³

Height h= 7.3cm

Radius r=?

To solve for the radius we need to substitute our data in the formula and solve for r

V= πr²h

189= 3.14*r²*7.3

189= r²*22.922

making radius subject of formula we have

r²= 189/22.922

r² =8.245

r= √8.245

r= 2.87

r= 2.9cm

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
