We know that
area of a rectangle=length*width
length=area/width
area=2.76 x 10^12 units²<span>
width=4.6 x 10</span><span>^5 units
</span>length=2.76 x 10^12/4.6 x 10^5 ------> 6 x 10^6 units
perimeter of a rectangle=2*[length+width]
width=4.6 x 10^5 units----> is equal to 0.46 x 10^6 units
length=6 x 10^6 units
perimeter of a rectangle=2*[6x10^6+0.46x10^6]----> 12.92 x 10^6 units
the answer is
12.92 x 10^6 units
Answer:
36000pi
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
We know the surface area
SA = 4 pi r^2
3600 pi = 4 pi r^2
Divide each side by 4pi
3600 pi / 4pi= 4 pi r^2/4pi
900= r^2
Take the square root of each side
30 = r
Now substitute into the equation for volume
V = 4/3 pi r^3
= 4/3(pi) (30)^3
=36000pi
For the point (2,5), 2 = x and 5 = y.
5= -2(2)
5 = -4
So no, the first one y=-2x would not work since -4 is not equal to 5.
5=2+3
5=5
Yes, that second one y=x+3 does work since 5 is equal to 5.
3 consecutive even integers : x, x + 2, x + 4
x + (x + 2) + (x + 4) = -84.....combine like terms
3x + 6 = - 84.......subtract 6 from each side
3x = -84 - 6
3x = - 90...divide both sides by 3
x = -90/3
x = -30
x + 2 = -30 + 2 = -28
x + 4 = -30 + 4 = -26
so ur 3 numbers are : -26, -28, -30
