Answer:
15.9 mm²
Step-by-step explanation:
We solve using Area of the circle formula
Area of a circle = πr²
Diameter of his friend's wand = 4.5mm
Radius = 4.5mm/2
= 2.25 mm
How much wire did his friend need to make the circular part of his wand? Use 3.14 for π
= 3.14 × (2.25mm)²
= 15.89625 mm²
Approximately = 15.9 mm²

Step-by-step explanation:
5+3+0+7=15
OCTA=8, an octagon has 8 sides, thus if one side is 6mm, then all sides, namely the perimeter, is 6+6+6+6+6+6+6+6, or 48.
now, we know what the apothem is.
Answer:
107 degrees
Step-by-step explanation:
The angles MNQ and RNP are equal to each other so you set them equal to each other, and solve for x. Than plug that value into either of the equations.
5x-18=4x+7
x=25
5(25)-18= 107
