Answer:
14 millimeters
Step-by-step explanation:
V=(4/3)πr³
1372π(1/3)=(4/3)πr³
1372=4r³ <em>(cancel out the pi and multiply both sides by 3)</em>
r³=343
r=7
Diameter is twice the radius = 2(7) = 14
Answer:
f(2)=0
Step-by-step explanation:
f(2)=2x-4
2(2)-4
4-4
0
Answer:
5y - 6x = 8 or y = 6x/5 + 8/5
Step-by-step explanation:
let M1= gradient of line AB and M2= gradient of the second line
When two lines are perpendicular, the product of their gradients is -1
i.e, M1M2= -1
M2= -1/M1
A(2,9) and B(8,4)
gradient= (y2-y1)/(x2-x1)
M1= (4-9)/(8-2)
= -5/6
M2= -1÷ -5/6
-1 × -6/5= 6/5
Equation of the line passing through C(-3,-2)
[y-(-2)]/[x-(-3)= 6/5
(y+2)/(x+3)= 6/5
5(y+2)= 6(x+3)
5y+10=6x+18
5y= 6x + 8
y= 6x/5 + 8/5
Answer:
30 inches
Step-by-step explanation:
The circumference of a circle can be found by using 2
r, or
* d.
Since we are given the circumference of the circle, 30
, you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.

To cancel out
you can divide both sides of the equation by pi. Now you have:
30 = d
Therefore the diameter of the circle is 30 inches.
