find the circumference and the area of the circle with the radius 9m use the value 3.14 for it do not round your answer be sure

kirill [66]

Explanation:

The circumference and the are of a circle with radius r

are:

$\begin{gathered} A=\pi r^2 \\ C=2\pi r \end{gathered}$

If we use pi = 3.14 and the radius is 9m:

$A=3.14\cdot(9m)^2=3.14\cdot81m^2=254.34m^2$ $C=2\cdot3.14\cdot9m=56.52m$

Answers:

• Area: ,254.34 m²

• Circumference: ,56.52 m

The tile along the edge of a triangular community pool needs to be replaced. A right triangles, where the hypotenuse is labeled

jolli1 [7]

Perimeter of a closed figure is the sum of length of its outline. The perimeter of the consider triangular pool is: $12x^2 + 8x + 25$ units.

<h3>How to calculate perimeter of a triangular figure?</h3>

Perimeter of a triangle = Sum of lengths of all its 3 sides.

For the given case, we have:

Length of first side(hypotenuse) = $8x^2$ units

Height = $4x^2 + 15$ units

Base is of length $8x + 10$

Thus, its perimeter is calculated as:

Perimeter of a triangle = Sum of lengths of all its 3 sides.

Perimeter = $8x^2 + 4x^2 + 15 + 8x + 10 = (8+4)x^2 + 8x + 25 = 12x^2 + 8x + 25$ units

Perimeter = $12x^2 + 8x + 25$ units

Thus,

The perimeter of the consider triangular pool is: $12x^2 + 8x + 25$ units.
