Answer:

28 cm

Step-by-step explanation:

<u>Circumference formula:</u>

C = πd

<u>Substitute values of circumference and the π to find the diameter:</u>

d = C/π
d = 88/3.14 = 28 cm (rounded)

Answer:

diameter = 28 cm

Step-by-step explanation:

circumference = 2πr

88 cm = 2 * 3.14.*r. ( π = 3.14 )

r = ( 88)/(3.14*2)

r = 14 cm

diameter = 2 * radius

diameter = 2 * 14 cm

diameter = 28 cm

Prove that the segments joining the midpoint of consecutive sides of an isosceles trapezoid form a rhombus.

sergiy2304 [10]

Answer:

See explanation

Step-by-step explanation:

a) To prove that DEFG is a rhombus, it is sufficient to prove that:

All the sides of the rhombus are congruent: $|DG|\cong |GF| \cong |EF| \cong |DE|$
The diagonals are perpendicular

Using the distance formula; $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$|DG|=\sqrt{(0-(-a-b))^2+(0-c)^2}$

$\implies |DG|=\sqrt{a^2+b^2+c^2+2ab}$

$|GF|=\sqrt{((a+b)-0)^2+(c-0)^2}$

$\implies |GF|=\sqrt{a^2+b^2+c^2+2ab}$

$|EF|=\sqrt{((a+b)-0)^2+(c-2c)^2}$

$\implies |EF|=\sqrt{a^2+b^2+c^2+2ab}$

$|DE|=\sqrt{(0-(-a-b))^2+(2c-c)^2}$

$\implies |DE|=\sqrt{a^2+b^2+c^2+2ab}$

Using the slope formula; $m=\frac{y_2-y_1}{x_2-x_1}$

The slope of EG is $m_{EG}=\frac{2c-0}{0-0}$

$\implies m_{EG}=\frac{2c}{0}$

The slope of EG is undefined hence it is a vertical line.

The slope of DF is $m_{DF}=\frac{c-c}{a+b-(-a-b)}$

$\implies m_{DF}=\frac{0}{2a+2b)}=0$

The slope of DF is zero, hence it is a horizontal line.

A horizontal line meets a vertical line at 90 degrees.

Conclusion:

Since $|DG|\cong |GF| \cong |EF| \cong |DE|$ and $DF \perp FG$ , DEFG is a rhombus

b) Using the slope formula:

The slope of DE is $m_{DE}=\frac{2c-c}{0-(-a-b)}$

$m_{DE}=\frac{c}{a+b)}$

The slope of FG is $m_{FG}=\frac{c-0}{a+b-0}$

$\implies m_{FG}=\frac{c}{a+b}$

What is 1 1/2 times 3?

Katarina [22]

$1 \frac{1}{2} = \frac{(1\cdot2) + 1}{2} = \frac{3}{2}$

$\frac{3}{2} \cdot 3 =\boxed{ \boxed{\boxed{\boxed{\boxed{\boxed{\bf{\frac{9}{2} = 4.5}}}}}}}}}}$

So your answer as a fraction is 9/2, while your answer as a decimal is 4.5.

Each square below represents one whole.

Usimov [2.4K]

Answer:

SQUARE 1:

100% ; 75%

Step-by-step explanation:

SQUARE 1:

If each square represents a whole ; the percentage of a whole = 100%

Dividing the square into 4 equal parts :

Percentage of each part :

100% ÷ 4 = 25%

Percentage represented by the shaded part:

(Percentage of each shaded part * number of shaded part)

(25% * 4) = 100%

SQUARE 2:

each square represents a whole ; the percentage of a whole = 100%

Dividing the square into 4 equal parts :

Percentage of each part :

100% ÷ 4 = 25%

Percentage represented by the shaded part:

(Percentage of each shaded part * number of shaded part)

(25% * 3) = 75%
