Answer:
64
mm² or approximately 201.06 mm²
Step-by-step explanation:
If the diameter is 16 mm, the radius will be 8 mm.
Use the circle area formula, A =
r², where r is the radius. Plug in 8 as r:
A =
r²
A =
(8²)
A = 64
So, the area of the circle is 64
mm² or approximately 201.06 mm²
Answer:
x=4 z=117
Step-by-step explanation:
Answer:
x = 135°
Step-by-step explanation:
6 sided polygon = hexagon
The sum of the interior angles of a hexagon = 720°
⇒ 4x + 90 + 90 = 720
⇒ 4x = 720 - 90 - 90
⇒ 4x = 540
⇒ x = 540 ÷ 4
⇒ x = 135°
Rotating the entire polygon should have no effect on its internal angles. I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions here in Brainly.
