The area of a circle whose radius is 19 centimeters is: 1,134 cm2
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
40.8cm
Volume of cylinder: p*49*8 = 1231.5 cubic units to one decimal place
circumference = 2 x π x radius = 2 x 3.14 x 15 cm = 94.2 cm
The area of a circle whose radius is 19 centimeters is: 1,134 cm2
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
The radius of a circle whose area is 3.14 square centimeters is: 1 cm
the area of a circle is pi times the radius squared. The diameter is 12, so the radius is 6 (half of the diameter). Therefore, the area is pi times 6 squared, which is 36 pi square centimeters. Also, if you want the answer in decimal, it's 113.09733552923255658465516179806 square centimeters.
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
40.8cm
Diameter is twice the radius, so 15 cm.
154 cm2
It is approx 1231.5 cubic units.
The question cannot be answered since the base of a cylinder is a circular area whose measurements should be in square units.Furthermore, the question contradicts itself. If the radius is 4 cm then the base cannot be 50 cm^2 and if the base is 50 cm^2 then the radius cannot be 4 cm.Finally, there is no information on the height of the cylinder.
the cylinder is approximately 50240 m3 the sphere is approximately 33493 and 1/3 m3
V = 1,608.5 cubic inches.
