If you unroll the cone you'll have a sector of a circle, where: i) radius of the sector = slant height of the cone, ii) arc length of the sector = circumference of the cone base. From i) l=r=7.5 From ii) Arc length = AL=angle/360 x 2 x pi x r = 2 x pi x R where r = radius of the sector and R = radius of cone base Angle = 360 degree - 38 degree = 322 degree so: R = (322 x 7.5) / 360 = 6.71 feet Height of the cone: l^2 = H^2 + r^2 (Pythagoras Theorem) H = 3.35 feet So, Volume = (pi x R^2 x H) / 3 Volume = 1577.87 feet^3 I hope this can help, Luciana Melo If you unroll the cone you'll have a sector of a circle, where: i) radius of the sector = slant height of the cone ii) arc length of the sector = circumference of the cone base From i) l = r = 7.5 feet From ii) Arc length = AL = angle/360 x 2 x pi x r = 2 x pi x R Where: r = radius of the sector R = radius of cone base angle = 360 degree - 38 degree = 322 degree Height of the cone: l^2 = H^2 + r^2 H = 3.35 feet So, Volume: V = (pi x R^2 x H)/3 V = 157.87 feet^3 I hope this can help, Luciana Melo
38: the diameter of a circle is twice its radius.
238.76
The radius is one-half of the diameter. Hence, the radius of a 76 in diameter circle is 38 in.
38 inches squared
To find the volume of a cylinder, you can use the formula V = πr^2h, where r is the radius and h is the height. In this case, since the dimensions are given in millimeters, convert them to the same unit. The radius would be half the diameter, so the radius is 190mm and the height is 930mm. Plug these values into the formula to find the volume in cubic millimeters.

38
If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.

V = Bh or V = πr^2h Since diameter is 6 cm, then radius is 3 cm. Substitute what you know into the formula and you have: 342 cm^3 = π[(3 cm)^2]h 342 cm^3 = π(9 cm^2]h divide by 9 cm^2 to both sides 38 cm = πh divide by π to both sides 38 cm/π = h or h = 38 cm/π h ≈ 12 cm

It is customary to call a circle a 38 inch circle if its diameter is 38 inches. If that is the case, the radius = diameter/2 = 19 inches.
Impossible to say. You question needs more detail, you need three variables to calculate volume; or two if you are calculating the volume of a cylinder. You also need to specify the units are 43 and 38 inches, feet, kilometers, millimeters?
Assuming that the three figures given are the length, breadth and height of a cuboid, it has a volume of 1681576 cubic units.
