4 0

Answer:

D=100

R=50

Step-by-step explanation:

Diameter can be found by dividing the circumference by pi (314/3.14=100). Dividing the diameter in halve is used to find the radius (100/2=50).

Graph the line with slope -2 passing through the point (4, 1)
Scrat [10]

Answer:

Use points (4,1) and (3,-1)

Step-by-step explanation:

Let's say the other coordinates are (x,y).

Then, we know (1-y)/(4-x)=2. So if y is -1, and x is 3, then we get:

[1-(-1)]/(4-3)=2/1=2

So draw the two points, (4,1) and (3,-1) on a coordinate plane, and use a ruler to make a line that goes through both the points.

If the perimeter of triangle ABC is 4 more than the perimeter of triangle ACD, what is the perimeter of quadrilateral ABCD? AD i
melisa1 [442]

Answer:

26 units.

Step-by-step explanation:

AB + BC + AC = AC + AD + DC + 4

AC is common so

AB + BC = AD + DC + 4

AB + BC - AD - DC = 4

Substituting the given values

AB + 7 - 5 - 6 = 4

AB = 4 - 7 + 5 + 6 =  8

So the perimeter of ABCD

= AB + BC + AD + CD

= 8 + 7 + 5 + 6

= 26.

The sides of ∆ABC inscribed in a circle are equidistant from the center. Tricia says that ∆ABC must be equilateral. Which explai
lisabon 2012 [21]

Answer:

Tricia is correct because the sides of the triangle are congruent since they are  equidistant from the center of the circle.

Step-by-step explanation:

Given that the sides of ΔABC inscribed in a circle are equidistant from the center. This implies the triangle is drawn within the circumference of the circle with a center.

Bisecting the three sides of the triangle shows that the three bisectors intersect at a point which is the center of the circle, and the lines are equidistant to this point. This proves that the length of the sides of the triangle are equal, so that the triangle is an equilateral triangle. Therefore, Tricia's statement is correct.
