Which figure below would include pi in the formulas for surface area and volume? a. cube b. cylinder c. pyramid d. tetrahedron

Option 'b' is correct.

Step-by-step explanation:

Since we know that

Surface area of cube = 6a²

Volume of cube = a³

So, it does not include pi at all.

Surface area of pyramid is given by

perimeter of base × height

Volume of pyramid is given by

× area of base × height

And we know that base can be of 2D shapes which do not include pi at all.

Surface of tetrahedron is given by

Volume of tetrahedron is given by

So, it does not include pi.

Surface area of cylinder is given by

Volume of cylinder is given by

Hence, only cylinder include pi.

Therefore, Option 'b' is correct.

(B) cylinder

Step-by-step explanation:

Since, we know that

(A)Surface area of cube is given as:

and

Volume of cube is given as:

Thus, both figures does not includes pi. Hence, this option is incorrect.

(B) Surface area of cylinder is given by:

and

Volume of cylinder is given as:

which includes pi, thus this option is correct.

(C) Surface area of pyramid is given as:

and

Volume of pyramid is given as:

And we know that base can be of 2D shapes which do not include pi at all.

Thus, this option is incorrect.

(D) Surface of tetrahedron is given as:

and

Volume of tetrahedron is given as:

which does not include pi. Hence, this option is incorrect.
