The answer is pi.
to find this, you find the circumference of a circle with a 4m radius, which is 2pi(4) or 8pi. then you need find the fraction of the circle that this angle is. a circle is 360degrees, so 45/360 is 1/8.

1/8 x 8pi = pi -> pi m

Answer:

Step-by-step explanation:

First find the circumference of a circle with radius 4

C = 2 * pi *r

C = 2*pi*4

C = 8pi

A circle has 360 degrees

Find the fraction of a circle that 45 degrees is

45/360 = 1/8

Multiply the fraction by the circumference

1/8 *8pi = pi

Complete the statement below to explain how this model shows that 1/6 ÷ 1/4 = 2/3.

Answer:

The answer is 2/3 and I will show the working to prove that in the explanation

Step-by-step explanation:

$\frac{1}{6}$ ÷ $\frac{1}{4}$

$\frac{1}{6}$ × $\frac{4}{1}$

Answer = $\frac{1}{6}$ × $\frac{4}{1}$ = $\frac{2}{3}$

So basically what is happening in the above steps what I have shown is that first I am changing the division sign into multiplication and then I am reciprocating the fraction of 1/4 into 4/1 because on the other side of it is multiplying and after doing that I am simplifying the fraction 4/6 by dividing it by 2 and hence I got a fraction of 2/3 as the answer

Answer:

x = 4

Step-by-step explanation:

A trapezium is a quadrilateral (has four sides and four angles) with one pair of parallel sides. A trapezium is said to be isosceles if the bases are parallel, the two other sides known as the legs are equal and diagonals of the trapezium are equal to each other.

In trapezoid ABCD, BC and AD are the diagonals.

Hence BC = AD (property of isosceles trapezoid)

9x + 1 = 12x - 11

Simplifying:

12x - 9x = 1 + 11

3x = 12

Dividing both sides by 2:

x = 4
