A cylinder has a volume of 198 and base has an area of 22 what is the height o the cylinder
Mumz [18]

Answer:

Step-by-step explanation:

The base of the cylinder is in the shape of a circle:

Area of the base=\pi *r^2

For Base area=22 square units

22=\pi *r^2

      22=3.14*r^2\\r^2=22/3.14\\r^2=7.01\\r=\sqrt{7.01}

Volume of the cylinder=\pi *r^2*h

For volume '198 cubic units' the height(h) is:

       198=\pi *r^2*h

       198=3.14*(\sqrt{7.01})^2*h

         198=3.14*7.01*h\\\\198=22.01*h\\\\198/22.01=h\\\\h=9 units\\

The length of one side of a square field is represented by the expression 3-7x.
Juliette [100K]

They give us the length of side of the square which is 3-7x.

To get an expression for the perimeter that is expressed as a product we have to multiply the expression 3-7x by four since every square has four sides. This will give us an expression of 4(3-7x). We than can use the distributive property to multiply everything inside the parenthesis by 4. This will give us an expression of 12-28x.
