Answer:
a = 9
Step-by-step explanation:
-6a + 2a = -36
-4a = -36
a = -36/-4
a = 9
Answer:
308 cubic meters.
Step-by-step explanation:
7 x 4 x 11 = 308
Answer:
16
Step-by-step explanation:
Lets solve this step by step,
First we insert 8 in x's place:
(8 - 4) + 12
Now we solve:
8 - 4 = 4
(4) + 12
4 + 12 = 16
Answer: 16

Answer:
Step-by-step explanation:
This equation is more intimidating than the problem you have to solve.
You know that the sine of everything is always between -1 and +1. So for the entire expression to be >= 0, the a*tan(pi/8) bit has to be 1 at least. Given this, we can forget about the sin(...) term of the equation for the remainder of solving it.
You already figured out that tan(pi/8) is sqrt(2)-1.
So what we're saying is a * (sqrt(2) - 1) has to be 1 at least.
If we solve a(sqrt(2)-1) >= 1 for a we get:
a = 1/(sqrt(2)-1)
<u>The expression that represents the volume of </u><u>the cone is 6aπ.</u>
What is called cone?
- A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the vertex.
- The volume of a cone is expressed as;
- V = (1/3)πr²h
- Where r is the radius, h is height and π is pie
Given the data in the question;
Radius r = 3
Height h = 2a
Volume of the cone V = ?
We substitute our given values into the expression above.
V = (1/3) × π × r² × h
V = (1/3) × π × (3)² × 2a
V = (1/3) × π × 9 × 2a
V = 18aπ / 3
V = 6aπ
Therefore, the expression that represents the volume of the cone is 6aπ.
