The total resistance in a circuit with two parallel resistors is 2 ohms and Ri is 6 ohms. Using the equation for R2, in terms of Rt and Ri, what is R2?

R₂ = 3 ohms

Step-by-step explanation:

It is given that,

The total resistance in a circuit with two parallel resistors is 2 ohms

The value of R₁ = 6 ohms

We need to find the value of R₂.

For a parallel combination, the total resistance is given by the formula as follows :

Putting all the values, in the above formula :

So, the value of second resistor is 3 ohms.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
