Answer:
(3,6)
Step-by-step explanation:
Y=X+3
Y=X2
X+3=2X
X-2X= -3
-x=-3
x=3
then Y=2X
Y=2×3
Y=6

The area of sector is 1.57 m²
<u>Explanation:</u>
Given:
Radius, r = 3 m
Central angle of a sector = 1/9π radians
Area of sector, A = ?
We know:
Area of sector, A = 
where,
α is the central angle in radians
On substituting the value we get:

Therefore, the area of sector is 1.57 m²
Answer:
11k +12
Step-by-step explanation:
8k + 4 and 3k + 8
Combine like terms
8k + 4 + 3k + 8
8k+3k + 4+8
11k +12
Answer:

Step-by-step explanation:
We need to find 1/4 of the area of a circle with a radius of 8
Let r be radius
Area of a circle = 
Substitute r with 8
Area of a circle = 
Now, to find 1/4 of the area, we can create an equation 
The answer is 
Hope this helps :)
