Answer:

Area of the Trapezoid is= $13.5cm^2$

Step-by-step explanation:

The given figure is in the shape of a trapezoid:

Area of a trapezoid= (1/2)*(Sum of parallel opposite sides)* (Distance between the parallel sides)

The parallel sides are: 6 cm and 3 cm

Distance between parallel sides= 3 cm

Area:

$=\frac{1}{2} *(6+3)*3\\\\=\frac{1}{2}*9*3\\\\=\frac{27}{2} \\\\=13.5 cm^2$

Area of the Trapezoid is= $13.5cm^2$

Step-by-step explanation:

If Sarah makes a profit of $ 4 on every necklace she sells, then:

4 necklaces = 4 * 4 = $ 16

6 necklaces = 6 * 4 = $ 24

8 necklaces = 8 * 4 = $ 32

10 necklaces = 10 * 4 = $ 40

Juan and his little brother Miguel ran around a circular track together. Juan ran on the inner track, which has a radius of 30 f

eduard

Answer:

80pi-60pi

Step-by-step explanation:

To find how much Juan ran, we must find the circumference.

pi *30*2=60*pi (which is how much Juan ran.)

pi*40*2=80*pi (which is how much Miguel ran)

80pi-60pi would be how much farther Miguel ran than Juan.

A flying disc has a circumference of 75.36 centimeters. What is the area of the flying disc? (Use 3.14 for .)

Hatshy [7]

The area of flying disk is 452.16 square centimeters

Step-by-step explanation:

The disc is in circular shape so we will use the formulas for circle in this question.

Given

Circumference = C = 75.36 centimeters

We have to find the area of the disc for which we have to find the radius first.

Let r be the radius

Then

Circumference is given by:

$C=2\pi r$

putting the values

$75.36 = 2*3.14*r\\75.36 = 6.28r$

Dividing both sides by 6.28

$\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm$

The area of circle is given by:

$A = \pi r^2$

Putting the values

$A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2$

Hence,

The area of flying disk is 452.16 square centimeters

Find the values of the variables

Jlenok [28]

Answer:

You can use Pythagoras theorem to calculate x:

12² + 14² = x²

144 + 196 = x²

x² = 340

x = √340 ≈ 18,44
