Question:

If the volume of a cylinder is 402 cubic centimeters and the radius is 4 centimeters, what is the height of the cylinder? Round to the nearest whole number.

Taylor D.

Answer:

The height is 8 centimeters. The formula to find the volume of a cylinder is V= pi*r^2*h. To solve the problem, you'd start with 402=3.14*(4^2)*h. To solve for h, you need to isolate it. Start with 4^2. That equals 16. Multiply 16 by pi (3.14). This gives you 50.27h=402. Divide 402 by 50.27 to solve for h. h=7.99, and based on rounding directions in the question, you round to 8 centimeters.

Question:

This question is an example of a question you might find in the English section of the ACT. Q: My trip to Greece was absolutely, fabulous and we had fun every day. A: a. No change b. My trip to Greece was absolutely fabulous and we had fun everyday. c. My trip to Greece was absolutely fabulous, and we had fun every day. d. My trip to Greece was absolutely, fabulous and we had fun every day.

Taylor D.

Answer:

The answer is c. because absolutely is the adverb of fabulous, which is an adjective describing the trip. You wouldn't want to separate these with a comma. Since it is a compound sentence, you want a comma between "fabulous" and "and". Every day should be two words because it is an adjective plus a noun that means 'each day', but everyday indicates that something is commonplace, like an everyday event.

Question:

x + 12 = 20. Solve for x.

Taylor D.

Answer:

x equals 8. To solve, you subtract 12 from 20 to isolate x. By subtracting 12 from 20, you find the difference between 12 and 20, which is 8. That means to find 20 when you have 12, you must add 8.
