What is the volume of a cone with diameter of 30 ft and height of 60 feet use 3.14 for pi enter your answer in the Box

Area of the top:

3.14 x 15^2 = 706.5 square feet.

Volume = area of top x height:

Volume = 706.5 x 60 = 42,390 cubic feet

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
