Answer:

2  11/12

Step-by-step explanation:

2 1/2 * 1 1/6

Change the mixed numbers to improper fractions

2 1/2 = (2*2+1)/2 = 5/2

1 1/6  = (6*1+1) /6 = 7/6

Replace with the improper fractions

5/2 * 7/6 = 35/12

Now we have to change it back to a mixed number

12 goes into 35 2 times   (2*12 =24)  

35 -12 = 11    with 11 left over

2 11/12

Answer:

35/12

Step-by-step explanation:

2 1/2 is 5/2

1 1/6 is 7/6

Multiply these together to get (5*7)/(2*6) or 35/12.

For the first one: A=pi*r^2*1/8 (1/8 becuase we are finding the area of one pane)
A=pi*16/8
A=2pi

For the second one: First do the larger circle minus the smaller circle (pretend they are whole circles)
A(larger)=pi*18^2
=324pi

A(smaller)=pi*8^2
=64pi

A=324pi-64pi =260pi

Now, a whole circle is 360 degrees so 150 degrees is 5/12 of a circle. We take 5/12 of 260pi to get the answer

260pi*5/12=340.3

Surface area???????????
MAVERICK [17]

Answer:

The option B is the correct answer. 79.18 m²

Step-by-step explanation:

Surface area = Base area +  Lateral surface area

Area of triangle = bh/2

b - base and h - height

<u>To find the base area</u>

We can consider the base is a hexagon.

A regular hexagon is a combination of 6 equilateral  triangle

Base area = 6 * area of triangle

base b = 3

<u>To find the height</u>

h =√[(6.2)² - (5.6)₂] = 2.7

Area of triangle bh/2 = (3 * 2.7)/2 = 3.99

Area of base = 23.95

To find lateral surface area

Lateral surface area = 6 * area of triangle

Area of triangle = bh/2 =(3 *6.2)/2 = 9.3

Lateral surface area = 6 * 9.3 = 55.8

<u>To find the total surface area </u>

Total surface area = Base area + lateral surface area = 23.95 + 55.8

= 79.75 m²

Therefore the option B is the correct answer. 79.18 m²
