Answer:

-3=9/5c +32

-3*5c=9/5c*5c+32*5c

-15c=9+160c

-15c -160c =9

c(-15-160)=9

c(-15-160)/(-15-160)=9/(-15-160)

c=9/(-15-160)

A test tube is cylindrical in shape with a length of 152 mm and a radius of 6.5 mm. What is the volume of the test tube? Report
vazorg [7]

Answer:

20165

Step-by-step explanation:

Given:

Length/height (h) of cylindrical test tube = 152 mm

Radius of cylindrical test tube = 6.5 mm

Volume = \pi r^2h

Required:

Volume of cylinder to nearest whole number

Solution:

The volume is given as V = \pi r^2h

Take π as 3.14 and plug the values of r and h into the volume formula.

V = 3.14*6.5^2*152

V = 3.14*6.5*152 = 20165.08

Volume of the test tube = 20165 mm³ (nearest whole number)
