Ahemisphere has a diameter of 26 centimeters. what is the volume of a sphere with the same radius? (use 3.14 for π. round the answer to the nearest tenth, if necessary. recall that the formula for the volume of a sphere is v=4/3pir^3.) a. 2,830.2 cubic centimeters b. 3,066.0 cubic centimeters c. 4,599.1 cubic centimeters d. 9,198.1 cubic centimeters

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
