The question is ambiguous because the units for the volume are not given The volume could be 704 cm3 or m3 or inches3. There is no intrinsic reason to assume one rather than another.
However, IF you assume the volume is in cm3, then
Volume, V = π r2h = π d2h/4
So d2 = 4V/Ï€h = 64.03 cm2
Then d = 8.002 cm.
Use Pythagoras' theorum a2 = b2 + c2 a2 = (9x9) + (12x12) 225 = 81 + 144 Ö225 = 15cm > 14cm. answer NO.
First, we should note that the formula for circumference is Dπ, or diameter times pi. Second, we should note that the diameter is simply double the radius. With this in mind, the circumference formula can then be turned into (2r)π C=2(14)π C=28π which is about equal to 87.96459
4cm
To find the answer you would do 161 divided by 14 because width plus length equals area. You just do the problem backwards. the answer ends up being width=11.5cm
To check whether it is possible to have a triangle with side lengths 4cm, 13cm, and 14cm, we use a special rule.The rule is: If you take any two sides of a triangle and add their lengths, the sum of the lengths must be greater than the third side.Test this triangle. 4+13=17, which is bigger than 14. 14+4=18, which is bigger than 13. 13+14=27, which is greater than 4.The rule works for all side combinations, so it is possible to have a triangle like this.So the answer is: yes, you can have a triangle of side lengths 4cm, 13cm, 14cm. (Note that the lengths do not have to be in centimeters, for example they can be 4m, 13m, and 14m)
Diameter = 14cm so radius = 7cm. Height = 5cm. Take pi as 22/7 Volume of a cylinder = pi*radius2*height Volume = 22/7*72*5 = 770 cubic cm.
The question cannot be answered. There is no information on what aspect of the cylinder is 14 cm: the radius, diameter, circumference, height.
Pi is a constant that is (roughly) equal to 3.14. You cannot arbitrarily take it to be 227! Area of a circle = pi*r2, where r = radius Volume of a cylinder = pi*r2*h, where h = height diameter = 2*r Therefore, r = diameter*1/2 Now, you have all the tools to calculate volume. This must be all illustrated in your textbook. Do your research first, which is called "studying".
The circumference of a circle with a diameter of 14cm is: 43.98 cm
A cone with a base radius of 9.9 cm and a height of 14 cm has a volume of 1,436.9 cm3
The surface area of a cylinder = height * 2 * pi * radius So, since we know the surface area, and the height, we can rearrange the equation: radius = Surface Area / (height * 2 * pi) = 88/(14 * 2 * pi) = 22/ (7*pi) = approx 1 cm. So the diameter, is 44/ (7*pi) = approx 2 cm.
Area is 98cm2
The diameter is 28cm
14cm
Use Pythagoras' theorum a2 = b2 + c2 a2 = (9x9) + (12x12) 225 = 81 + 144 Ö225 = 15cm > 14cm. answer NO.
First we must find the radius: Curved surface area of the cylinder excluding the two end pieces = 88 cm2 2*pi*radius*14 = 88 Divide both sides by 2*pi*14 radius = 1.000402499 cm Volume = pi*1.0004024992*14 Volume = 44.01770994 cubic cm
CSA of cylinder = 2 * pi * r * hSo, 264 = 2 * pi * r * hVolume of cylinder = pi * r2 * hSo, 924 = pi * r2 * hStep 1pi * r2 * h /2 * pi * r * h = 924 / 264Or, r / 2 = 924 / 264Or, r = 924 * 2 / 264Or, r = 7Therefore, Radius = 7cm and Diameter = 2r = 14cmStep 2Or, 2 * pi* 7 * h = 264Or, 44h = 264Or, h = 264 / 44Or, h = 6Therefore, Height = 6cmTherefore, Height is 6cm and Diameter is 14cm
