What does the water level in a cylinder rise by when a sphere is submerged in it when I know the radius of the sphere and the radius of the cylinder?

Fist you've got to find the volume of the sphere, if the radius was 4cm then it would be...4/3*pi*r3=268cm V of cylinder= pi*r2*l (the radius for example is 8cm) 268=pi*64*l L=268/64pi =1.3cm

What is circumference if A 64pi?

If by ' A 64 pi' you mean the Area. Then A = 64pi Since A = pi r^2 and 64 is 8^2 Then we can say r(radius)= 8 The circumference of a circle is C = 2pir Hence C = 2 x 3.14 x 8 C = 16 x 3.14 C = 50.24 linear units. The value for 'pi' at 3.14 is an approximation.

What is the radius of a circle if it had a 90 degree sector and an area if 64pi?

From your question, we can't tell whether [ 64 pi ] is the area of the circleor the sector.The area of a circle is [ pi R2 ].If [ 64 pi ] is the area of the circle, then the radius is [ 8 ], and we don't careabout the sector.If [ 64 pi ] is the area of the sector, then the area of the full circle is [ 256 pi ](because the 90-degree sector is 1/4 of the circle), and the radius is [ 16 ].


Given a cylinder with radius 8 in and height 11 in find the area of a cross section that is parallel to its base. Leave your answer in terms of pi.?

The area of a cross section of a cylinder that is parallel to its base is equal to the area of the base. In this case, the base of the cylinder is a circle with a radius of 8 inches. Therefore, the area of the cross section is 64pi square inches.


What is the diameter of a circle whose area is quadrupled when the length of its radius is increased by 4cm?

The answer to your question is 8 cm diameter, increasing to 16 cm diameter: r2 squared = 4 x r1 squared and r2 = r1 + 4 r1 squared + 8r1 + 16 = 4r1 squared 3r1 squared - 8r1 - 16 = 0 Factors are (3r1 + 4)(r1 - 4), so original radius was 4cm (area 16pi) and increased radius is 8 cm (area 64pi).
