q^2 – r^2

Correct Incorrect Correct answer

q + r

Correct Incorrect Correct answer

q – r

Correct Incorrect Correct answer

If A = pi*h(R + r), express r in terms of the other letters.

r = (A – pi*h*R) / (pi*h)

Correct Incorrect Correct answer

r = (A – pi*h*R) / h

Correct Incorrect Correct answer

r = (A – pi*R) / (pi*h)

Correct Incorrect Correct answer

r = (A – pi*R) / h

Correct Incorrect Correct answer

The kinetic energy formula is KE = 1/2mv^2. Express m in terms of the other letters.

m = 2KE / v^2
