Formula for volume:
πr^2(h/3)
Diameter divided by 2 is the radius
18/2 = 9
radius: 9 units
Use pythagorean theorem to find height
x^2 + 9^2 = 15^2
225 - 81 = 144
x^2 = 144
x = 12
height: 12 units
Plug these number in the volume formula.
Thus, it should be looking as:
π9^2(12/3) = 1017.88
Answer:
1017.88 
Answer:
180/45 = 4/1, he did 4 situps in 1 second.
A $0.85 x 2= amount for shipping.
B $0.85-0.05 = total cost for each pound
so the equation would be.
$0.85-0.05 = 0.8
0.8x2 = cost for 2 pounds of toys shipped
1.60 is the cost for 2 pounds hope this helped
31 1/2 miles is how much he would have traveled in 7 hours
Answer:
A linear function can be written in the slope intercept form or a point slope form of a line. Where a table is given for values representing the function, the ordered pairs will represent points on the line.The gradient of the line is a ratio of rise to run from the table values.In slope intercept form, the gradient and initial value of the function are indicated.
For example in a function f(x)=mx+b , m is the gradient of the line and b is the y-intercept value of the function.
To find the slope, m, you divide the difference between y-values by the difference in corresponding x-values of any two points on the line.
A decreasing linear function has a negative slope; if m<0 then f(x)=mx+c is decreasing
An increasing linear function has a positive slope where m>0.
