Answer:
5.73cm
Step-by-step explanation:
Given parameters:
Circumference of the circle = 36cm
Unknown
Length of the radius = ?
Lets represent the radius by r
Solution
The circumference of a circle is the defined as the perimeter of a circle. The formula is given as:
Circumference of a circle = 2πr
Since the unknown is r, we make it the subject of the formula:
r = 
r = 
= 
= 5.73cm
Answer:
x=6, x=0
Step-by-step explanation:
+ 
= 25
+ 
= 25
x=6, x=0
Answer:
m=0
Step-by-step explanation:
The slope is m=0 and the Y intercept should be b= -4 .
Answer:
The distance between the parallel sides is 20cm.
Step-by-step explanation:
Area of a trapezoid:
where a and b are the 2 bases, and h is the height. The value we're trying to find here is the height.
3 of the 4 variables in this equation are already given:
A = 800
a = 48
b = 32
Just plug those in and solve for h:
Answer: -2
Step-by-step explanation: The line has a slope of -2/1, which is just -2.
