Answer: 340 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Circumference = 2π radius
Replacing with the circumference value and solving for r:
31.416 =2π r
31.416 /2π =r
5cm =r
And then:
Volume of a cone = 1/3 x π x radius^2 x height
Replacing with the values given:
V = 1/3 π (5)^2 (13) = 340 cm3
Feel free to ask for more if needed or if you did not understand something.
Answer:
x = 5
Step-by-step explanation:
Hello!
For this equation, we start by combining like terms. Since we have two terms with the same variable, we are able to add them together:
3x + 2x + 7 = 32
5x + 7 = 32
As you can see, we added 3x and 2x together.
Now, since we are aiming to get x by itself, we need to subtract 7, from both sides:
5x + 7 = 32
5x = 25
Finally, we divide the 5 attached onto the x by itself, which will leave the x alone on one side:
5x = 25
x = 5
Again, we divided on both sides.
And, there you have it!
x = 5
Hope I helped!

The standard form of quadratic function is:
f(x) = a x² + b x + c
where: a - a leading coefficient, c- constant term:
a = 2, c = -3
Answer: D) f( x ) = 2 x² + 3 x - 3
