Dr. lamb is mixing a solution for his next patient. he has a cylindrical test tube which is 4 inches across on the inside. the depth of the tube is 9 inches. of 1 cubic inch of space holds 3 liters of water, about how many liters of water are left in the test tube ?

 There are 34.35 liters left in the test tube.

Step-by-step explanation:

Since we have given that

Depth of the tube = 9 inches

Circumference of base=4 inches

As we know the formula of circumference ,

Now, we need to find the volume of tube is given by

Since we have also given that,

Of 1 cubic inch of space holds 3 liters of water,

So,

Hence, there are 34.35 liters left in the test tube.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
