density = mass/volume → density = 84 g / 12 cc = 7 g/cc = 7 g/cm³ = 7 g/ml

This is missing some information. For instance, it does not say what 84 is. Is it the radius, the circumference? See the link below for a step by step guide to finding a diameter.

Volume = (84) x (1/6) = 14 cubic feet = 0.52 cubic yard

84 = 84

on apex it would be 84m^3 :)

The volume of a cylinder is pi*(radius)^2*height. We are not given the radius here, but we know the circumference. Circumference is 2*pi*radius. So radius is equal to the circumference/(2*pi). We can then substitute this into the equation for volume to get: V=pi*(circumference/(2*pi))^2*height=(circumference)^2/(4*pi)*height._________________________________________________________________For your problem we have circumference=84 inches and height=32 inches. So:(84 inches)^2/(4*pi)*32 inches=7056 square inches/(4*pi)*32 inches=1764 square inches/pi*32 inches=56448 cubic inches/pi=17967.9564553 cubic inches which is about 17968 cubic inches.

1028.1567 gallons Volume of a cylinder is (Pi) x (radius of cylinder)2 x (height of cylinder) There are 231 cubic inches in 1 gallon, so I converted the feet to inches prior to calculating the volume. Therefore: Volume=(3.14159)(30)2(84)=237504.2 inches3 Divide that by 231 and you get 1028.1567 gallons.

Circumference = 48 = 2*pi*r inches so radius = 48/(2*pi) = 24/pi = 7.64 in Also, height = 7 ft = 12*7 = 84 inches Then volume = pi*r2*h = pi*(7.64)2*8 = 15401 cubic inches, approx or 8.91 cu ft.

Assuming you are asking for the surface area of a cylinder of height 84 in and circumference (of end) of 26 in: 12 in = 1 ft circumference = 2 x π x radius → radius = circumference ÷ (2 x π) surface_area = 2 x area_of_ends + curved_area = 2 x π x radius2 + height x circumference = 2 x π x (circumference ÷ (2 x π))2 + height x circumference = circumference2 ÷ (2 x π) + height x circumference = (26 ÷ 12 ft)2 ÷ (2 x π) + (84 ÷ 12 ft) x (26 ÷ 12 ft) ≈ 15.91 sq ft

The solution is derived as follows:First, the formula for determining volume is V=(pi)r2hNext, substitute values for the various components:(pi) = 3.141592654 r = 20 h = 84So... v = (3.141592654)(202)(84) = (3.141592654)(400)(84)When solved completely, v = 105,557.51 units(Since no actual unit of measure was listed (inches, centimetres, etc.), I simply used "units" in their place.)

area = 1/2 base x height =84 height = 84/7 = 12 meters

That will depend on the height of the triangle which has not been given. Base = (84*2)/height

For a start it wont be cubic inches because a circle is 2D BUT if u mean there is a cylinder 12" long which has a cross sectional area or 84" then the volume will be 1008 cm cubed

Volume of Cylinder = Ï€(Diameter, ft)2 (Height, ft)Take note of the formula4convert 84 inches in feet84in=7ftÏ€ (7ft)2 * 16-4 = Ï€ *49*16-4= 3.142*12.25*16=615.832 Gallons

There are three feet in one yard so you must first convert the dimensions to yards. The diameter would be 12 2/3 yards and the height would be 28 yards. V= 14, 106.27 cubic yards
