Which equation can be used to find V, the volume of the cylinder in cubic centimeters?
* V = π ( 7 )^2h
* V = π ( 7h )^2
* V = π ( 14 )^2h
* V = π ( 14h )^2
The diameter is 14 and the height is unknown
The correct equation to find the volume of the cylinder in cubic centimeters would be:
V = π ( 7 )^2h
Which choice could you use to find the volume of the given sphere? ( π = 3.14 )
* V = 4 ( 3.14 ) ( 4.5 )^3
* V = 4/3 ( 3.14 ) ( 4.5 )^2
* V = 4/3 ( 3.14 ) ( 4.5 )^3
* V = ( 3.14 ) ( 4.5 )^3
Determine the volume of the given sphere. (nearest tenth)
* 91.1 cubic units
* 286.1 cubic units
* 381.5 cubic units
* 401.6 cubic units
The correct equation to find the volume of the given sphere is:
V = 4/3 ( 3.14 ) ( 4.5 )^3
To determine the volume of the sphere, we can substitute 4.5 for the radius and calculate as follows:
V = 4/3 ( 3.14 ) ( 4.5 )^3
V ≈ 381.5 cubic units
Therefore, the volume of the given sphere is approximately 381.5 cubic units.
Oh sorry there was also a Ramender for part A which is 4.5
In that case, the correct equation to find the volume of the given sphere is:
V = 4/3 ( 3.14 ) ( 4.5 )^3
To determine the volume of the sphere, we can substitute 4.5 for the radius and calculate as follows:
V = 4/3 ( 3.14 ) ( 4.5 )^3
V ≈ 381.6 cubic units
Therefore, the volume of the given sphere is approximately 381.6 cubic units.
What is the volume of the cone to the nearest cubic meter? ( Use π = 3.14 )
* 21 m^3
* 84 m^3
* 168 m^3
* 335 m^3
The tip of the cone is 5m amd the bottom is 4m
The formula to find the volume of a cone is given by:
V = (1/3)πr^2h
where r is the radius of the base and h is the height of the cone.
In this case, the radius of the base is 4m and the height is 5m. We can substitute these values into the formula and calculate the volume:
V = (1/3)(3.14)(4^2)(5)
V ≈ 83.73 m^3
Rounded to the nearest cubic meter, the volume of the cone is approximately 84 m^3.
Therefore, the correct answer is:
* 84 m^3
A gift box in the shape of a cylinder has a diameter of 8 inches and a height of 12 inches. Which measurement is closest to the total surface area of the gift box in square inches?
* 402.12 in^2
* 301.59 in^2
* 1,005.31 in^2
* 603.19 in^2
To calculate the total surface area of a cylinder, we need to find the sum of the areas of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is given by:
A = 2πr^2 + 2πrh
where r is the radius of the base and h is the height of the cylinder.
In this case, the diameter of the cylinder is 8 inches, so the radius (r) would be half of that, which is 4 inches. The height (h) is given as 12 inches.
We can substitute these values into the formula and calculate the surface area:
A = 2π(4)^2 + 2π(4)(12)
A ≈ 301.59 in^2
Therefore, the measurement closest to the total surface area of the gift box is 301.59 in^2.
Therefore, the correct answer is:
* 301.59 in^2
In each case, determine if the sides form a right triangle. If they do, place in the Yes column. If they do not, place in the No column.
There are two boxes named one yes and one no and four cases which are the cases that on choice will be placed in which of the two boxes with the first case being 9, 12, 14 and the second being 6, 9, 12 and the third being 5, 12, 13 and finally the forth being 3, 4, 5
