True or false? The circumcenter of a triangle is the center of the only circle that can be circumscribed about it

Dafna11 [192]

Answer:

The statement is true.

Step-by-step explanation:

Given the statement we have to tell the statement is true or false.

The statement is

"The circumcenter of a triangle is the center of the only circle that can be circumscribed about it"

The circumcenter of triangle is the point in the triangle where the perpendicular bisectors of sides intersect.

The center of the circumscribed circle is the the point where the perpendicular bisectors of the sides meet.

Hence,

The circumcenter is also center of the triangle's circumcircle - the circle that pass through all three of the triangle's vertices.

Therefore, the given statement is true.

The circumference of a circle is 23π m. What is the area, in square meters? Express your answer in terms of \piπ

LenaWriter [7]

Answer:

Area of the circle = $\frac{529}{4}$ π m² or 132.25 π m²

Step-by-step explanation:

To find the area, we will follow the steps below.

First write down the formular for the circumference of a circle, then use the formula to find the radius of the circle after which you can now find the area of the circle.

That is;

C = 2πr

where c is the circumference of the circle and r is the radius of the circle

From the question given, circumference C = 23π

23π = 2π r

Divide both-side of the equation by 2π

23π/2π = 2πr/2π

23/2 = r

radius = $\frac{23}{2}$ m

Formula for calculating the area of a circle is given by;

A = πr²

where A= area of the circle and r is the radius of the circle

A = π ( $\frac{23}{2}$ )²

A = $\frac{529}{4}$ π m² or 132.25 π m²

Area of the circle = $\frac{529}{4}$ π m² or 132.25 π m²
