a base of a cylinder is a circle so its area is calculated just like that of a circle: d=5 so r=5/2=2.5
a= π r2= π (2.5)2
The curved surface area is 125.66 square inches.
It depends whether you want lateral or surface area. Lateral area is only the area of everything except the two bases. Surface area is the total area. Lateral area formula: pH or perimeter(of base) x height In this case, since this is a cylinder, the perimeter will be pi(diameter). Surface area: pH + 2B B= area of base So the equation would be: 10pi(9) + 2(pi x 5 squared)
Any height. The size you have has the base about that of a tin of paint. But it could be any height.
It is sqrt(29) units.
The surface area of a cylinder is given by the formula 2πr(r+h), where r is the radius and h is the height. In this case, the radius is half the diameter, so it is 4 inches. Thus, the surface area of this cylinder is 2π(4)(4+5) = 2π(4)(9) = 2π(36) ≈ 226.195 square inches.
40pi or about 125.6
The diameter cannot be "8 in and 5 in".
The cylinder's total surface area is about 227.77 units2
Base area = pi*r2 = 78.5 sq cm
207.2
A cylinder with a radius of 5 centimeters and height of 9 centimeters
It depends whether you want lateral or surface area. Lateral area is only the area of everything except the two bases. Surface area is the total area. Lateral area formula: pH or perimeter(of base) x height In this case, since this is a cylinder, the perimeter will be pi(diameter). Surface area: pH + 2B B= area of base So the equation would be: 10pi(9) + 2(pi x 5 squared)
The curved surface area is 125.66 square inches.
Any height. The size you have has the base about that of a tin of paint. But it could be any height.
The square root of 29 You can use pythagoras.
It is sqrt(29) units.
To solve this we need to find the area of the tank in cubic feet, and then convert that to gallons. The volume of a cylinder can be found by multiplying the area of its base by its height. The area of a circle is equal to Pi×r2, where r is the radius of the circle. The radius is half of the diameter, so the area of the base of the tank if Pi×12, which equals Pi. Multiply this by 5 to find that the volume of the tank is 5 Pi cubic feet. Convert this to gallons to find that the volume is 117.5 gallons.
