Answer:
area of the circle = 36π cm²
But area of a circle = πr²
Which means,
πr² = 36π
r² = 36π/π
r² = 36
r = √36 = 6 cm
Radius = 6 cm
Answer:
multiplication
Step-by-step explanation:
Answer A. point. To make a plane, it has to have a minimum of 3 lines or more. A line is just a line.
The angle of rotation of a polygon is found using the formula 360/n
Where n is the number of sides.
Shape 1: 360 / 10 = 36
Shape 2: 360 /4 = 90
Shape 3: 360 /5 = 72
Shape 4: 360/8 = 45
Shape 5: 360/3 = 120
Shape 6: circles = 1
Shape 7: 360 /6 = 60
Shape 8: 360 / 12 = 30
There are 3 shapes that are 72 or higher.
