What is the exact volume of a cylinder that has a height of 1.8 ft and a radius of 6.1 ft?_____π ft³

Answers

cylinder area=height times area of base (area of base=area of circle)

height =1.8
radius=6.1
area of circle=pi times r^2


area of circle=pi times 6.1^2=37.21π
times height

1.8 times 37.21π=66.978π

volume=66.978π ft^3

A square has side length 6 inches. A parallelogram has a base of 6 inches. The area of the square is equal to the area of the parallelogram. What is the height of the parallelogram? How do i solve this?

Answers

The area of a parallelogram is base x height thus height will be 6 inches.

What is a parallelogram?

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

As per the given,

Area of square = 6 x 6 = 36

Area of parallelogram = 6 x height

Height x 6 = 6 x 6

Height = 6

Hence " The area of a parallelogram is base x height thus height will be 6 inches".

Fine the area of a circle with a radius of 7 in. Write the formula, substitute, solve.

Answers

Formula: A=(pi)r^2

Substitution: A=3.14(7^2)

                     A=3.14(49)

Solve: A=153.86 in^2


*I personally like to use the pi sign on my calculator to multiply the radius squared by, but my keyboard did not have a pi sign.  Usually, the pi sign is more exact.  If you used the pi sign, your answer would be 153.94 inches^2.  Hope this helps!
