Salutations!
Radius = 7cm
Area of circle = [tex] \pi r^2[/tex]
= [tex]3.14*7*7[/tex]
= [tex]153.94 cm^2[/tex]
[tex]153.94[/tex] rounded to the nearest tenth = [tex]153.9cm^2[/tex]
Hope I helped (:
Have a great day!

Answer:
[tex]153.9\ cm^{2}[/tex]
Step-by-step explanation:
Hello, thanks for asking this question here at Brainly, I think I can help you with this
the area of circle is given by:
[tex]Area=\pi * radius^{2} \\[/tex]
Step one
Let
[tex]\pi =3.14\\and\\r= 7 cm[/tex]
Step two
put the values into the equation
[tex]Area=\pi * radius^{2} \\Area=3.14* (7 cm)^{2}\\ Area=3.14* 49\ cm^{2} \\Area=153.9\ cm^{2} \\[/tex]
Hence, the area of a circle with radius 7 cm is 153.9 cm2
I hope it helps,do not hesitage in asking me anything about this, have a great day
