Answer:
41cm
Step-by-step explanation:
The circumference of a circle is 82π
Therefore r can be calculated as follows
2 × π × r= 82× π
2πr= 82π
r = 82π/2π
r= 41
Hence r is 41cm
Just multiply 4*12 and add 6.
answer =54
Answer:
33/40
Step-by-step explanation:
cross multiply
5 x 5 = 25
8 x 1 = 8
25 + 8 = 33 (our numerator)
8 x 5 = 40 (our least common denominator)
You just do
3x=x+4
subtract x from both sides
2x=4
divide 2 from both sides
x=2
y=2+4
y=6
(x,y)= (2,6)
Given:
The triangle ABC rotated 270 degrees clockwise.
The rule of rotation is

To find:
The coordinates of point B after the given rotation.
Solution:
From the given graph, it is clear that the coordinates of point B are (4,4).
The given rule of rotation is:

Using this rule, we get

The coordinates of point B after the given rotation are (-4,4).
Therefore, the correct option is C.
