Answer:
6.3 × 10⁶ square miles
Step-by-step explanation:
We are given,
The radius of the moon is approximately 1000 miles.
We know that the moon resembles a sphere and also,
Area of sphere =
, where r is the radius.
Now, the area of the moon =
= 1.26 × 10⁷ square miles
Since, only the half of the area is clear to view.
So, the area left to view =
= 6.3 × 10⁶ square miles.
Hence, the area of the moon in view is 6.3 × 10⁶ square miles.
Answer:
radius= 14
Step-by-step explanation:
the distance around the edge is given by = 2πr
88= 2 (22/7)*r⇒ r= 88*7/44= 14
Answer:
Step-by-step explanation:
1
2
is equivalent to 6
12
because 1 x 12 = 2 x 6 = 12
2
4
is equivalent to 6
12
because 2 x 12 = 4 x 6 = 24
3
6
is equivalent to 6
12
because 3 x 12 = 6 x 6 = 36
4
8
is equivalent to 6
12
because 4 x 12 = 8 x 6 = 48
Answer:

Step-by-step explanation:
For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is
.
Answer:
ummmm..... let's see..
Step-by-step explanation:
using "Almighty formula"
{Y = –x +/– √b^2 – 4ac / 2a}
so we name all the values behind the coefficients which are; –1^2, 8 and 11
so let's assign a,b,c to these values:
a =–1, b =8, c = 11
all you just do now is to add these values to the formula
you should be having Y =1 +/– √8^2 – 4×–1×11
———————————
2×–1
Y =1 +108
———— or Y = 1–108
–2 –––––
–2
now add and divide to get Y.
(your answer will be two)
