Answer:
Step-by-step explanation:
Given: The radius is 6 cm
To find the area + circumference we need to use 2 formulas:
Area: pi* radius^2
Circumference: 2*pi*r
First we can do the area
I will use "pi" for pi instead of 3.14
pi * 6^2
= 36 pi
The area is 36 pi
Next, circumference
2 * pi *r
2*pi*6
= 12 pi
So the area is 36 pi, and the circumference is 12 pi
Answer:20cm
Step-by-step explanation:
Circumference=20π
Diameter=circumference ➗ π
Diameter=20π ➗ π
Diameter=20
Diameter=20cm
Perpendicular slope: flip sign and reciprocal = 2
Y = 2x + b
Plug in point (8,5)
5 = 2(8) + b
5 = 16 + b
b = -11
Equation: y= 2x - 11
Answer:
Yes
Step-by-step explanation:
4/10 = 0.4
4/100 = 0.04
0.4 > 0.04
Therefore the answer is yes
