Answer:
89.80 cm cubed
Step-by-step explanation:
A hemisphere is essentially just half of a sphere. We want to find its volume.
The volume of a sphere is denoted by: V = (4/3)π * r³, where r is the radius. That means the volume of a hemisphere, which is half a sphere, will be denoted by: V = (1/2) * (4/3)π * r³ = (2/3)π * r³.
Here, the radius is 3.5, so plug this in:
V = (2/3)π * r³
V = (2/3)π * (3.5)³ ≈ 89.80 cm cubed
Answer:
The equation of parabola is standard form is 
Step-by-step explanation:
Given equation of parabola is,

In order to find the equation of parabola in standard form, eliminate x from left side of equation and use completing square method to find the equation.
First step is to add x on both side of equation.


Rewriting,

Now applying completing square method as follows.
Following are the steps for calculation of this method.
Find the last term of above equation by using below formula,

Now coefficient of y is 8.

Simplifying,


Second step is to add and subtract the last term.

Rewriting,

Since 
Using above formula,

Therefore, the equation of parabola in standard form is 
Answer:
57/100
Step-by-step explanation:
This is the answer because:
1) Since 0.57 in the hundredths place, the denominator is going to be 100
2) We have 57 of a 100, therefore, 57 is going to be the numerator
3) Now, our fraction is 57/100
4) We cannot simplify this fraction any further because they do not have any common multiples or factors
Hope this helps!
