What is the surface area of a cylinder formula?

The surface area of a cylinder is given by the formula: SA = 2πr(h + r), where r is the radius and h is the height.

How do you find the volume of a sphere?

The volume of a sphere is calculated using the formula: V = (4/3)πr³, where r is the radius.

Explain how to multiply fractions.

To multiply fractions, multiply the numerators together and the denominators together: (a/b) × (c/d) = (ac)/(bd).

What is the formula for the volume of a rectangular prism?

The volume of a rectangular prism is calculated by the formula: V = length × width × height.

How do you add fractions with different denominators?

To add fractions with different denominators, find a common denominator, convert the fractions, and then add the numerators.

What is the formula for the surface area of a cube?

The surface area of a cube is calculated using the formula: SA = 6a², where a is the length of a side.

How do you divide fractions?

To divide fractions, multiply by the reciprocal of the divisor: (a/b) ÷ (c/d) = (a/b) × (d/c).

What is the surface area of a cone formula?

The surface area of a cone is given by the formula: SA = πr(r + l), where r is the radius and l is the slant height.

How do you convert a mixed number to an improper fraction?

To convert a mixed number to an improper fraction, multiply the whole number by the denominator, add the numerator, and place that over the original denominator.

What is the volume of a pyramid formula?

The volume of a pyramid is calculated using the formula: V = (1/3)Bh, where B is the area of the base and h is the height.
