Mathematics

Answer:

100 m^2.

Step-by-step explanation:

The area of a trapezoid = (h/2) (a + b) where h = the perpendicular distance between the 2 parallel sides and a and b are the lengths of the 2 parallel sides.

Here we have Area = (1/2 * 10) ( 8 + 12)

= 5 * 20

= 100 m^2.

Answer:

100

Step-by-step explanation:

So first you add the two bases 12+8=20. Then you multiply the sum to the height 20×10=200. Lastly, you divide that number by two 200÷2=100.

For a circle with a radius of 15 cm, what is the length of an arc intercepted by an angle measuring 120°?
slega [8]

Answer: 31.43 cm

Step-by-step explanation:

The length of an arc  is calculated using the formula:

\frac{theta}{360} X 2\pir

where : theta is the angle in degree

r = radius

If the angle is given in Radian , the length can be calculated using the formula:

L = r∅

Since , the angle is given in degree , we will use the first formula.

L = \frac{theta}{360} X 2\pir

L = \frac{120}{360} X 2 X π X 15

L = \frac{1}{3} X 2 X \frac{22}{7} X 15

L = \frac{660}{21}

L = 31.42857143

L ≈ 31.43 cm
