Answer:

1.99 meters

Step-by-step explanation:

The equation for a circumference is $C=2\pi r$ , therefore if the circumference is 12.56 meters:

$12.56=2\pi r$

$r=\frac{12.56}{2(3.14) } =1.99$ meters

The diagonals of a rhombus intersect at the point (0,4). If one endpoint of the longer diagonal is located at point (4,10), wher

Answer:

The other endpoint is located at (-4,-2)

Step-by-step explanation:

we know that

The diagonals of a rhombus bisect each other

That means-----> The diagonals of a rhombus intersect at the midpoint of each diagonal

so

The point (0,4) is the midpoint of the two diagonals

The formula to calculate the midpoint between two points is equal to

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

we have

$M=(0,4)$

$(x_1,y_1)=(4,10)$

substitute

$(0,4)=(\frac{4+x_2}{2},\frac{10+y_2}{2})$

<em>Find the x-coordinate $x_2$ of the other endpoint</em>

$0=\frac{4+x_2}{2}$

$x_2=-4$

<em>Find the y-coordinate $y_2$ of the other endpoint</em>

$4=\frac{10+y_2}{2}$

$8=10+y_2$

$y_2=-2$

therefore

The other endpoint is located at (-4,-2)

Kevin is making a picture frame. He has a piece of trim that is 4 feet long.How many 14−inch-long pieces can Kevin cut from the

Lerok [7]

First, convert 4 feet into inches - 48 inches. Then, divide 48 by 14 to get 3.43, so he can have 3 14-inch long pieces. To get the left over out of a foot, take 14 x 3 to get 42, then subtract 42 from your original 48 inches to get 6 inches left, which is half of a foot.

Solve: 3(2d-1) - 2d=4(d-2)+5

nadezda [96]

3(2D-1)-2D = 4(D-2)+5
6D-3-2D = 4D-8+5
4D-3 = 4D-8+5
4D-3 = 4D-3
4D = 4D-6
0 = -6
The answer is C, no solution

In circle A shown below, Segment BD is a diameter and the measure of Arc CB is 36°: Points B, C, D lie on Circle A; line segment

iris [78.8K]

Answer:

The answer is $m$

Step-by-step explanation:

The triangle isosceles has two equal angles and two equal sides

The triangle ABC is an isosceles triangle -----> see the attached figure

$AC=AB$ -----> radius of the circle

$m$ ------> angles of the base of the isosceles triangle ABC

$m$ ------> by central angle ( vertex angle of the isosceles triangle ABC)

Remember that

the sum of the internal angles of a triangle is equal to $180\°$

so

$m$

$36\°+2m$

$m$
