Answer:

B)113.04 cm^2

Step-by-step explanation:

circumference is 37.68

C=2πr

now the Area is

A=πr^2

we need to know the radius

so 37.68=2(3.14)r

divide both sides by 2(3.14)

get

r=6

now solve for area

A=(3.14)(6)^2

=113.04

If an isosceles triangle ABC has a vertex B, and AB=6×+3, BC<br> BC=8x-1, and AC=10x-10, find x
saw5 [17]

Using the given information, the value of x is 2

<h3>Calculating the length of the leg of an isosceles triangle</h3>

From the question, we are to determine the value of x

From the given information,

The isosceles triangle ABC has its vertex at B

If the vertex is at B, then we can conclude that

AB = BC (<em>Legs of an isosceles triangle are equal a</em>)

Also, from the given information,

AB = 6×+3

BC = 8x-1

Thus,

6x + 3 = 8x - 1

Collect like terms

3 + 1 = 8x - 6x

4 = 2x

2x = 4

∴ x = 4/2

x = 2

Hence, the value of x is 2
