Answer:
144
Step-by-step explanation:
12X12 is also 12+12+12+12+12+12+12+12+12+12+12+12
Lets simplify that though.
12(10)+12(2) (since 10 plus 2 is 12)
120+24
144
The value of x is 27 units from the given circle, if the radius of the circle is 18 units.
Step-by-step explanation:
The given is,
Circle diagram, with radius of 18
Step:1
Given circle contain right angular triangle,
Ref attachment,
x = 18
y = 12
Where,
x = a + b...................(1)
a = b
a =
b =
From Pythagoras theorem,
Substitute the values,
Take square root on both sides,
a= 13.416
Step:2
From equation (1),
x = 13.416 +13.416
x = 26.833
x ≅ 27
Result:
The value of x is 27 units from the given circle, if the radius of the circle is 18 units.
Answer:
C. a 180° rotation about its center
Step-by-step explanation:
The question is on rotation of an object about the origin through 180°
When a point B, (h,k) is rotated about the origin 0 through 180° both clockwise and anticlockwise directions , the new position is B'(-h,-k)
Example, if we have point K (5,8) rotated through 180°, clockwise or anti-clockwise about the origin the new position will be; K'(-5,-8)
