AM: Unit 3 Practice Test final

Front

What is the formula to calculate force?

Back

The formula to calculate force is F = ma, where F is force, m is mass, and a is acceleration.

Front

How do you solve for mass in the equation F = ma?

Back

To solve for mass (m), rearrange the equation to m = \frac{F}{a}.

Front

What is simple interest?

Back

Simple interest is calculated using the formula I = Prt, where I is interest, P is principal, r is rate, and t is time.

Front

How much simple interest is earned on a principal of $2,000 at an 8% rate for 5 years?

Back

The simple interest earned is $800.

Front

What is the diameter of a circle?

Back

The diameter of a circle is the distance across the circle through its center.

Front

How do you find the radius of a circle if the diameter is known?

Back

The radius is half of the diameter. If the diameter is 12 feet, the radius is 6 feet.

Front

What is the formula for the volume of a sphere?

Back

The formula for the volume of a sphere is V = \frac{4}{3} \pi r^3.

Front

What is the volume of a sphere with a radius of 6 cm?

Back

Using \pi = 3.14, the volume is approximately 904.32 cubic centimeters.

Front

What is the formula for finding the area of a circle?

Back

The formula for the area of a circle is A = \pi r^2.

Front

What does π (pi) represent in mathematics?

Back

π (pi) is a constant approximately equal to 3.14, representing the ratio of the circumference of a circle to its diameter.
