Then

which is a disk of radius 1, hence with area
.
Answer:
about 113.04 square inches
Step-by-step explanation:
No angles are indicated, so we must assume the sector is 1/4 of the circle. Then its area is 1/4 of that of a circle with radius 12 in:
Circle area = πr²
Sector area = (1/4)π(12 in)² = 36π in²
Sector area ≈ 36(3.14) in² = 113.04 in²
Y=2x
3x+2y=21
3x+2(2x)=21
3x+4x=21
7x=21
x=3
y=2(3)
y=6
Answer:
1,2,5
Step-by-step explanation:
On edge
Answer:
-30.
Step-by-step explanation:
We are dividing by a negative number to get a positive one, so we need the other number to also be negative.
We can re-write this as -5 * 6
This can be simplified into -30.
