Answer:
38.46≅38.5
Step-by-step explanation:
Area = П
r = diameter / 2
= 7/2
r =3.5
Π= 3.14
Area = 3.14 × = 38.46
to the nearest tenth = 38.5 in
Answer:
[tex]38.5in^{2}[/tex]
Step-by-step explanation:
Area of a circle = [tex]\pi r^{2}[/tex]
Radius of circle = [tex]7\times\frac{1}{2}[/tex]
[tex]= 3.5[/tex]
So, [tex]\pi r^{2} = \pi \times 3.5^{2}[/tex]
[tex]= \pi \times 12.25[/tex]
[tex]= 38.48451...\\[/tex]
[tex]= 38.5[/tex] ([tex]1[/tex] d.p)
[tex]\therefore[/tex] the area of the circle is [tex]38.5 in^{2}[/tex] rounded to the nearest tenth place.
Hope this helps :)
