To get the surface area of the sphere, we need to know the radius. Since the volume is given, we can get the radius.
Volume =
π r³
5000πm³ =
π r³
5000m³ =
r³
5000m³ x 3 = 4r³
=
<span>
</span>∛3750 = ∛r³
r = 15.536m
r = 15.54m
Since the radius is now known, substitute it directly to the surface area formula
A = 4π x r²
A = 4π x (15.54)²
A= 3,034.67 m² or 3,035 m²
Answer:
1)
Part l: N+5
Part ll: 4+3 - 3
Part lll: x/2 - 7
Part lV: 5-4(m)
2)
Part l: 6(x)= 22
Part ll: 2(n) +7 = 19
Part lll: t^2 - 3 = 46
Part IV: m:n -2 =10
3)
Part l: $400
Part ll:
week 0-220
week 1-140
week 2-170
week 3-200
week 4-230
Part lll: W/2 = m
Part IV: $640- to show your work just add $60 to each week
4)
$96 - $48= $48= CD player
Answer:
hi I was wondering if I could come in
So if you're solving by substitution, one equation must be in slope intercept form. Ill just go with the first one.
-4x+y=6
<u>+4x +4x
</u>y=6+4x
Now substitute the value of y in for the value of y in the second equation:
-5x-(6+4x)=21
-5x-6-4x=21
-9x-6=21
<u> +6 +6
</u><u>-9x=27
</u>-9 -9
x=-3
Now input that into the first equation:
-4(-3)+y=6
12+y=6
<u>-12 -12</u>
y=-6
I HOPE THIS WAS HELPFUL! If it was, please rate my answer!
