Cylinder a has a radius of 1 and a height of 4. cylinder b has a radius of 2 and a height of 4. find the ratio of the volumes of the two cylinders. (there is not supposed to be a picture for this problem - if you'd like, you may draw the cylinders to find the ratio of the volumes.)

Ascientist has 50 grams of a radioactive element. the amount of radioactive element remaining after t days can be determined using the equation (1) after two days the scientist receives a second shipment of 50 grams of the same element. the equation used to represent the amount of shipment 2 remaining after t days is 10) - 50 which of the following is an equivalent form of the expression for the amount remaining in shipment 2? what’s the answer?
