What we know:
3.14 pi
radius: 7in.
Result units: in^3, this is the results of in used for radius; no conversion needed
Formula volume of a sphere: (4/3)* pi * r^3
(4/3)(3.14)(7)(7)(7)
(4/3)(3.14)(343)
(4/3)(1077.02)
(1.3)(1077.02) \\repeated 3 infinite
1436.026666\\repeated 6inf
The volume of the sphere is about 1436.0266 in^3
Answer:
For any depth y, y, the width will be given by 2 x, 2 x, so we need to solve the equation above for x x ... 2 − 3 Add 3 to both sides. x + 3 = (y − 2) 2 ... .4 n 100 + n represents the concentration C C of an acid solution after n n mL of 40% solution has been added to 100 mL of a 20% solution. First, find the ..
Step-by-step explanation:
23 3/4 rounds because you can take 95 divided by 4 to get 23 3/4 rounds
Asuuing yo meant (h,k)=(-5,1/2)
equation is
(h,k) is center and r=radious
given that (h,k)=(-5,1/2) and r=1
h=-5
k=1/2
if you wanted us to expand
x
²+y^2+10x-y+25.25=1
Answer:
The positive integer is 3.
Step-by-step explanation:
Let 'x' be the integer
Given that five times of a positive integer is less than twice its square by 3.
so
5 times of x =
3 less than twice of the square of x =
so the equation becomes
Factorise
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
solving
Subtract 1 from both sides
Simplify
Divide both sides by 2
Simplify
Also solving
Add 3 to both sides
simplify
Thus, we got integers:
x = 3 or x = -1/2
- As x can not be a negative integer according to the question.
Therefore, the positive integer is 3.
