Answer:
113.04
Step-by-step explanation:
All you have to do is substitute the r in the equation.
And of course pi is equal to 3.14
V = 4/3(3.14)3^3
That gives you a volume of around 113.04
<h2>Answer: y = x - 1</h2>
<h3>Step-by-step explanation:
</h3>
<u>Find the slope of the parallel line</u>
When two lines are parallel, they have the same slope.
⇒ if the slope of this line = 1
then the slope of the parallel line (m) = 1
<u>Determine the equation</u>
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line: (5, 4)
⇒ y - 4 = 1 (x - 5)
∴ y - 4 = x - 5
We can also write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:
since y - 4 = x - 5
<h3> y = x - 1</h3>
To test my answer, I drew a Desmos Graph with the information provided in the question and my answer.
Answer:
V= πr²h
V= 72π
V= 226.2
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder
Given data
Radius r of cylinder 3
Height h of cylinder 8
We know that the volume of a cylinder is given as
V= πr²h
Substituting our given data we have
V= π3²*8
V= π9*8
V= 72π
V= 226.2
We know that
center (−1, 4) and <span>passes through the point (3, −5)
</span><span>the value for the radius is,
using the Distance Formula---------r=</span>√(4+5)²+(-1-3)²=√(9²+(-4)²
r=√97
<span>equation for a standard form for a circle
(x-h)</span>²+(y-k)²=r²
<span>the center is (h,k)-----------> (-1,4)
</span>(x+1)²+(y-4)²=(√97)²---------------> (x+1)²+(y-4)²=97
the answer is
(x+1)²+(y-4)²=97
Answer:
Area is square units so if length is tripled (times 3), area is times 3^2 or 9
so 600•9 = 5400 cm^2
