Answer:
V≈4188.79
Step-by-step explanation:
The formula of the volume of a sphere is V=4/3πr^3
Answer:
4.) y= 3x-2 6) y= 4
Step-by-step explanation:
4.
m= 3 , (-2,-8)
y-(-8) = 3(x-(-2))
y+8= 3x+6
y= 3x-2
6.
m= 0 , (5,4)
y- 4= 0(x-5)
y= 4
y= 4
Answer:
4x^2 +84x+440
840 in^2
Step-by-step explanation:
The length of the picture and frame is x+ 22+x= 2x+22
The width of the picture and frame is x +20+x = 2x+20
Area is length times width
A = (2x+22) *(2x+20)
We can FOIL to find the area
first 2x*2x = 4x^2
outer 2x*20 =40x
inner 2x*22 = 44x
last = 22*20 = 440
Add these together
4x^2 +40x+44x+440
4x^2 +84x+440
b. x=4
4x^2 +84x+440
4(4)^2 +84(4) +440
4*16 +336+440
64+776
840
