Please Answer the 27the question I will mark you as the brainlest
kondor19780726 [428]

Answer:

Step-by-step explanation:

1) we have to find the area of the cut out portion

Since both circles in one side makes up the side 28cm

The diameter of each circle is 14cm

radius = diameter / 2

r = 7cm

Area of a circle = πr²

A = 22/7 × 7²

= 22/7 × 7 × 7

= 22 × 7 = 154cm²

So the four circles will make

= 154 + 154 + 154 + 154

= 616 cm²

The Area of the square will be

= L × L

= 28 × 28

= 784 cm²

Therefore the area of the remaining portion will be

Area of the square - total area of the circles

= 784 cm² - 616 cm²

= 168 cm²

The area of the remaining part is 168 cm²

the exterior angle of a regular polygon is one third the size of its interior angle. how many sides does the polygon have
Aloiza [94]

Answer:

8 sides

Step-by-step explanation:

let x be the exterior angle then 3x is the interior angle

interior angle + exterior angle = 180° , then

x + 3x = 180

4x = 180 ( divide both sides by 4 )

x = 45

the sum of the exterior angles of a polygon = 360°

since the polygon is regular with each exterior angle = 45°, then

number of sides = 360° ÷ 45° = 8

Translate and solve 5 greater than m is no more than 65
Nadusha1986 [10]

Answer:

m ≤ 60    (look at the picture)

Step-by-step explanation:

<em>5 greater than m is no more than 65</em>

m + 5 ≤ 65             <em>subtract 5 from both sides</em>

m + 5 - 5 ≤ 65 - 5

m ≤ 60
