Answer:
The area of the circle is 50.24 mm
²
Step-by-step explanation:
To solve this exercise we need to use the area formula of a circle:
a = area
r = radius = 4mm
π = pi = 3.14
a = π * r²
a = 3.14 * (4mm
)²
a = 3.14 * 16mm
²
a = 50.24 mm
²
The area of the circle is 50.24 mm

5/6, .23, -5 3/8, .324....
Answer:
-122
Step-by-step explanation:
18- {5 [34-(17-11)]}
Work inside out.
18- {5 [34-(17-11)]}=
=18- {5 [34-(6)]}=
=18- {5 [28]}=
=18-{140}=
=-122
If the question was written correctly, the answer should be -122.
Hope this helps!
