Answer:

diameter(d)=8 in.

radius(r)= d/2= 4 in.

height(h)= 3r = 3(4) = 12 in.

Volume=r ² h

          =(3.14)(4)²(12)

          =(3.14)(16)(12)

          =602.88 in.

      Therefore, the volume of the cylinder is 602.88 in.

Answer:

130

Step-by-step explanation:

since bc and bd equal the same thing, plug in every answer option until you get to 360.

(130 x 2) = 260

plus cd = 100.

260 + 100 = 360.

The arc length is twice the inscribed angle.

The sum of the three angles must be 180.

The measure of the arc length BC is 130°

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangle BCD is isosceles and BC ≅ BD.

Isosceles triangle C B D has points on the circle.

The measure of arc CD is 100 degrees.

This means,

We know that the arc length is twice the inscribed angle.

2 x Angle B = CD

2 x Angle B = 100

Angle B = 100/2

Angle B = 50

Now,

In an isosceles triangle, the angle opposite to the equal sides must be equal.

The sum of the three angles must be 180.

x + x + 50 = 180

2x = 180 - 150

2x = 130

x = 65

Now,

We know that the arc length is twice the inscribed angle.

So,

The measure of the arc length BC.

= 2 x 65

= 130°

Thus,

The measure of the arc length BC is 130°

Answer: For 1, the answer is B since there is no rational number for sqrt17.

For 2, the answer is C since it has to be less than 11 whose square is 121 and larger than 10 whose squre is 100.

For 3 the answer is B. Just plug the x value into the equation. => y=1/2(-1)-2 => y= -1/2-2 => -2 1/2.

For 4 the answer is A because the graph first goes up then stys their staticly for a while then plumets down. It fits the description of the first one.

Area:  200.96 cm

Circumference:  50.24 cm

Explanation: I recently just learned this.  The area of a circle is Pi times radius squared which makes.  3.14 x 8^2 = 3.14 x 64 = 200.96.  SInce none of the original measurements are squared it will be    200.96 cm

The circumference of a circle is diameter times pi which makes  3.14 x (8 x 2) = 3.14 x 16 = 50.24.  Since none of the original measurements are squared it will be 50.24 cm

Answer: 1 1/12 yards

Step-by-step explanation:

Since Ciara needs 2 ⅓ yards of fabric for the shawl and also needs 1 ¾ yards of fabric for the dress, the total yards needed will be:

= 2⅓ + 1¾

= 2 4/12 + 1 9/12

= 3 13/12

= 4 1/12 yards

Since she has 3 yards of fabric, the number of yards needed more will be:

= 4 1/12 - 3

= 1 1/12

Therefore, she needs 1 1/12 yards more.

Answer:

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

Step-by-step explanation:

The sum of interior angles of a triangle = 180°

From the above question, one of the angles = 60°

The value for the two other interior angles = 180° - 60° = 120°

Hence, the following options could be the values of x and y is given as x + y = 120

Therefore,

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

DG = 16 cm

Step-by-step explanation:

DG is one- third of AD , then

DG = [tex]\frac{1}{3}[/tex] × 48 = 16

The length of the segment DG will be equal to 16 cm.

Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial qualities such as figure distance, shape, size, and relative position. A geometer is a mathematician who works in the field of geometry.

Given In the diagram below of triangle ABC, medians AD, BE and CF intersect at point G  and the length of AD is 48 cm.

The length of the segment DG will be calculated as,

DG is one-third of AD, then

DG = ( 1 / 3 ) × 48

DG = 16

Therefore, the length of the segment DG will be equal to 16 cm.
