Answer:
r = 4
Step-by-step explanation:
2r = 13 + -5
2r = 8
r = 4
Hope that helps!
Answer: the answer is 7
Step-by-step explanation:
Area of quadrilateral= Length x Width
a+5 times a-2 = 60 which is the area
7+5 times 7-2= 60
12 times 5= 60
Therefore, a equals 7
Answer:
y = (-1/4)x + 9/4
Step-by-step explanation:
2y = 8x - 6
So, y = 4x - 3 (Slope = 4)
Slope of perpendicular line = -1/4
Equation of line: y-3 = (-1/4)(x-(-3))
y-3 = (-1/4)x - 3/4
y = (-1/4)x + 9/4
I think it would be the last one from my calculations im not positive but its what makes sense.
The formula for the circumference of a circle is
C = 2π·r
or
r = C/(2π)
The radius r of cylinder A is
r = (4π)/(2π) = 2
The formula for the area of a circle is
A = π·r²
or
r = √(A/π)
The radius of cylinder B is
r = √(9π/π) = 3
The dimensions of cylinder A must be multiplied by 3/2 to produce the corresponding dimensions of cylinder B.
