Answer:

A=12x²+13x-14

Step-by-step explanation:

Area=Length×width

A=(4x+7)(3x-2)

A=4x(3x-2)+7(3x-2)

A=12x²-8x+21x-14

A=12x²+13x-14

A cone has a diamete of 3 inches the cone hold 12 cubic inches of water to the nearet inch what is the height of the cone
Andre45 [30]

Volume for a cone is 1/3 pi * r^2*h, where r is radius and h is height. We have diameter = 1/2 radius. Thus, radius = 1.5in. We also have volume is 12 in. Using formula for volume of a cone and plugging in what we know, we have 12 = 1/3*pi*(1.5)^2*h, were solving for h. To get, h= (12*3)/(pi*(1.5)^2), which is approximately 5.0931in, 5 inches
