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 :)
