The quarter is a circular coin with a diameter of 24.26 millimeters and a thickness of 1.75 millimeters. What is the volume of a stack of 20 quarters to the

nearest cubic millimeter?

Hint

8090

64,714

32,357

16,179

16,179 mm3

Step-by-step explanation:

First we need to calculate the volume of one coin:

V = t * (pi*d^2)/4

Where V is the volume, t is the thickness and d is the diameter.

So, we have:

V = 1.75 * (pi * 24.26^2)/4 = 808.9274 mm3

Now, as we have a stack of 20 coins, to find the total volume, we just need to multiply the volume of one coin by 20:

Total Volume = 20 * V = 20 * 808.9274 = 16,178.55 mm3

The nearest cubic millimeter is 16,179 mm3

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
