The volume of the cone is 25.12cm cubed, and the area of the base is 12.56cm squared. what is the height

Height of the cone having volume as and base area is 6 cm.

Solution:

Given that volume of cone =

Area of base =

Need to determine height of the cone.

Formula for volume of the cone is as follows

Area of circular base of cone =

Replacing in equation (1), we get

In our case Volume of cone and Area of base

On substituting the values of volume and area in equation 2 we get

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!

b. f(x) = –√x + 3this is the correct answer
