U11Q2 Practice

Front

What is the Surface Area Ratio of similar solids if the ratio of their corresponding linear dimensions is 4:1?

Back

16:1

Front

What is the formula for the volume of a cylinder?

Back

V = πr²h, where r is the radius and h is the height.

Front

If the dimensions of a figure are multiplied by a factor of k, how does the volume change?

Back

The volume changes by a factor of k³.

Front

What is the density of an object?

Back

Density is defined as mass per unit volume (Density = Mass/Volume).

Front

If a cylinder's radius is doubled, how many times larger is its volume?

Back

4 times larger.

Front

Calculate the volume of an oblique cylinder with a radius of 3 and a height of 9.

Back

81π units³.

Front

What happens to the volume of a solid if its dimensions are reduced to one-third?

Back

The new volume will be 1/27 of the original volume.

Front

How do you calculate the density of an object?

Back

Density = Mass / Volume.

Front

What is the volume of a cylinder with a radius of 5 and a height of 10?

Back

250π units³.

Front

If the surface area of a solid is 64 cm², what is the surface area of a similar solid with dimensions doubled?

Back

256 cm².
