What is the length of the arc EF?

The length of the arc EF is calculated by applying the formula for the length of an arc as shown below;

EF = θr

where;

θ is the angle subtended by the arcr is the radius of the sector

From the given diagram, the radius of the arc = 4, and the angle subtended by the arc = π/2

The length of the arc is calculated as follows;

EF = ( π/2 ) x 4

EF = 2π

6>w/-2 solve the inequalities

Answers

Answer:

Step-by-step explanation:

6>w/-2 (Given)

6>-w/2 (Rewrite)

12>-w (Multiply both sides by 2)

-12<w (Remember to flip the sign when dividing or mulitplying by a negative)

w>-12 (Rewrite with w in front)

Therefore, w>-12 is the solution to the inequality.

Answer:

w>-12

Step-by-step explanation:

First, you you need to get rid of the -2 in w/-2 by multiplying -2 by both sides like this.

(-2)6>w/-2(-2)

Then you simplify it like this:

-12>w

However, since you multiplied/divided with a negative, you switch the inequality sign like this:

w>-12

Parallelogram ABCD is a rhombus. Side BC = 5cm and segment AO = 3.8cm
What is the area of ABCD?
What is the length of diagonal BD?

Answers

The area of the rhombus ABCD is 24.7 cm².

The length of diagonal BD is 6.5 cm.

What is the area of a rhombus?

A rhombus have equal four sides and the diagonals of the rhombus divides it into four equal right triangles. The area of the rhombus is the sum of individual areas of the four right triangles.

The hypotenuse side of the right triangle = side of the rhombus = BC = 5 cm

One of the legs of the right triangle = AO = OC = 3.8 cmLet the second leg of the right triangle = OB = OD =  x

The second leg of the right triangle is calculated as follows;

[tex]x^2 + 3.8^2 = 5^2\\\\ x^2 = 5^2 - 3.8^2 \\\\ x^2 = 10.56\\\\ x = \sqrt{10.56} \\\\ x = 3.25 \ cm[/tex]

The area of one right triangle of the rhombus is calculated as follows;

[tex]A = \frac{1}{2} (3.8)(3.25)[/tex]

The area of the rhombus ABCD is calculated as follows;

[tex]A = 4 \times \frac{1}{2} (3.8)(3.25)\\\\ A = 24.7 \ cm^2[/tex]

The length of diagonal BD is calculated as follows;

[tex]BD = OB \ + \ OD\\\\ BD = x \ + \ x\\\\ BD = 3.25 \ cm \ + \ 3.25 \ cm\\\\ BD = 6.5 \ cm[/tex]

Which of the following is three dimensional and indefinitely large ?

Answers

Complete question is;

Which of the following is three-dimensional and infinitely large?

A. A solid

B. A line

C. A plane

D. Geometric space

Answer:

D. Geometric space

Step-by-step explanation:

The answer is option D.

A one dimensional object has only length, a two dimensional object has length and breadth, while a 3 dimensional object has length, breadth and depth.

Thus, a line is a one dimensional object because it has just length.

A plane is a two dimensional object.

While a solid and geometric space are both 3 dimensional objects.

However, solid is finitely large while geometric space is infinitely large.
