Search Results<span>Let L denote the line of intersection. Then v = a × b = (1 − 1,−(−2 − 1),2 − (−1)) = (0,3,3) is parallel to L. We only need to find a point P on L. To find P, solved the system of equations of the planes: 2x − y + z = 5 and x + y − z = 1. We consider P to be the point of L on the plane z = 0.</span>
It is a semicircle so you'd use this formula for the area:
πr² / 2
Then substitute 2 into r and solve (2 because it's the radius, 4 is the diameter)
You would use this formula for the perimeter:
(πd / 2) + d
or
πr + 2r
Then substitute 4 into d / 2 into r and solve.
Hope I helped :)
Answer:
parallel
Step-by-step explanation:
- y=-3/5x slope = -3/5
- y=5/3x slope = 5/3
- PARALLEL LINES have the SAME SLOPE
- PERPENDICULAR LINES have NEGATIVE RECIPROCAL SLOPE
The rectangle area: 7•8= 56
The circle area: pi d^2/4= 3,14•6^/4= 28,26^2
56-28,26= 27,74 cm2
