Acone has a diameter of 8 centimeters and a height that is 4 times the diameter. using 3.14 for pi, which of the following can be used to calculate the volume of the cone?
one over three(3.14)(32cm)2(4cm)
one over three(3.14)(32cm)2(8cm)
one over three(3.14)(4cm)2(32cm)
one over three(3.14)(8cm)2(32cm)

The volume of a cone is given by the formula

... V = (1/3)π·r²·h

You have a radius of 4 cm and a height of 4·8 cm = 32 cm, so this becomes

... V = (1/3)π·(4 cm)²·(32 cm)

This seems to match your 3rd selection, ...

... one over three(3.14)(4cm)2(32cm)

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
