Answer:
(4.4, 4.4)
Step-by-step explanation:
The point S can be found as the weighted average of the end points. The relative weights are the reverse of the distances to the end points:
RS : ST = 1 : 4
S = (4R +1T)/5
S = (4(2, 2) +(14, 14))/5 = (22, 22)/5
S = (4.4, 4.4)
Y=4 (-2)=-8
y=4 (1)=4
y=4 (2)=8
Answer:
So i say C
Step-by-step explanation:
240 = area
The perimeter of a rectangle is calculated as
Perimeter= 2(length + breadth )
So, Perimeter = 2*length + 2*breadth
Now we are given the length as 34.2 meters and breadth as 27.8 meters
So the perimeter will be
2(34.2+27.8) meters
which equals 2(62) meters
Hence Perimeter = 124 meters
To solve this problem, we simply use the equation of
volume for hollow cylinders:
V = π h (R^2 – r^2)
where V is volume, h is height = 10, R is outer radius =
8.4/2 = 4.2, r is inner radius = 6/2 = 3
V = π (10) (4.2^2 – 3^2)
<span>V = 86.4π = 271.43 mm^3</span>
