As we’ve seen, for a circuit with two resistors arranged in parallel, we can calculate the total resistance in the circuit, RT in ohms, with this equation. RT=(R1*R2) / (R1+R2)

The radius of the base of a cylinder is 10 centimeters, and its height is 20 centimeters. a cone is used to fill the cylinder with water. the radius of the cone's base is 5 centimeters, and its height is 10 centimeters.

The base of a triangle exceeds the height by 7 centimeters. if the area is 400 square centimeters, find the length of the base and the height of the triangle.
