1) 1/4th of a circle is called a quadrant.and its angle is =Angle at the centre of the circle(360°)X1/4 i.e.,=360°X1/4=90°.therefore angle is 90°.
2)circle divided into two equal parts is called a semi circle.And angle that divides the circle is angle at the centre of the circle(360°) ×1/2 i.e., =360°×1/2 i.e.,=180°.therefore the angle is 180°.
3)The circular loaf is to to be cut into 9 equal parts.And the angle at which the loaf should be cut is = angle at the centre of the circle(360°) ×1/9 i.e., = 360×1/9 i.e., =40°

Answer:
Tina earned $11.5
Step-by-step explanation:
From the question, we are told that Tiana earns 2.50 less than twice what is earned by Add
let us have x as what is earned by Add
Thus, we have what is earned as 2x-2.5
Now Add, earned 6.50, so we want to know what Tina earned
That would be;
2(6.5) - 2.5
= 13-2.5
= 10.5
If you counted the inside spaces you would be finding area instead of perimeter.
Answer:
he did a full circle turn around
Step-by-step explanation:
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km
