Answer: Apply the formula for the volume of a sphere.
Step-by-step explanation:
The volume of a sphere is
4
π
r
3
3
We just need to insert
r
=
2
c
m
into this to get the volume.
4
π
2
3
3
=
32
3
π
The exact volume is
32
3
π
c
m
3
The approximate volume is
33.5103217
Answer:
Obviously, it's 2
Step-by-step explanation:
First, 1 is 1x1, so branch out under both 1's and put 1 x 1. Then, you add 1 + 1 + 1 + 1, which is 4. Then you do 4 - 2 since it is the two 1's in the original problem, and you get 2.
This is SUPER extra...
As well as mathematically incorrect lol
Answer:
I think it is -5
I am actually not sure
Step-by-step explanation:
Answer:
25
Step-by-step explanation:
Right angled triangle
Solve for hypotenuse
This is the formula <em>c=√(a^2+b^2)</em> so pug in the numbers a=24 b=7 √(24^2 + 7^2)=c=25
1) -5y=-x-10 /:(-5)
y = 1/5 x + 2 m=-5 ( perpendicular lines )
5=(-5)* 2 + b
5 = -10 + b b = 15
y = -5 x+15
2) -5 y = -10x+8
y = 2 x - 8/5 m = 2
4= 2 * 2 + b
4 = 4 + b b=0
y = 2 x
3 ) y = -4 x-1 m = -4
0 = 5*(-4)+b
0 = -20 + b b = 20
y=-4 x+20
4) 2 y = -4 x + 5
y = -2 x + 5/2 m = -2
5 = (-2) * (-3) + b
5 = 6 + b b = -1
y = -2 x - 1
5) -3 y = - x + 9
y = 1/3 x - 3 m = -3
5 = -3*3+b
5 = -9 + b b = 14
y = -3 x + 14
