Answer:
x = 4, y = 6, z = 2
Explanation:
Let x, y and z represent the 3 digit.
Where:
x = 2z
y = 3z
z = z
And: x + y + z = 12
2z + 3z + z = 12
6z = 12
z = 2
If z = 2 then:
x = 2(2) = 4
y = 3(2) = 6
The answer is 12π.
To get the volume of the cone, we need the height. The radius is given.
V = πr² × (h/3)
The total surface area of the cone is:
SA = πr² + πrl where r is radius and l is slant height
24π = π(3)² + π(3)(l)
24π = 9π + 3πl
24π - 9π = 3πl
15π = 3πl
l = 15π / 3π
l = 5
Using Phytagoras, we can calculate the height of the cone:
l² = h² + r²
5² = h² + 3²
25 - 9 = h²
h = √16
h = 4
Therefore the volume is:
V = π(3)² × (4 / 3)
V = 3π × 4
V = 12π
<h3>
Answer:</h3>
10.
<h3>
Step-by-step explanation:</h3>
In order to find the missing value, we need to divide 173.1, by 17.31:
173.1 / 17.31 = 10
Dividing the product (173.1) by one value in the equation (17.31) can represent what the missing value is, in order for 17.31 to equal 173.1
<h3>
Check:</h3><h3>
</h3>
17.31 · 10 = 173.1
173.1 / 10 = 17.31
He needs to measure out 8 times because there are 2 scoops in each batch and 4 times 2 is 8.
Hope this helps!!
