Question

What is the area of a circle with a radius of 7 cm? (Use 3.14 for pi and round to the nearest tenth.)

Answer 1

Salutations!

Radius = 7cm

Area of circle = $\pi r^2$

                      = $3.14*7*7$

                      = $153.94 cm^2$

$153.94$ rounded to the nearest tenth = $153.9cm^2$

Hope I helped (:

Have a great day!

Answer 2

Answer:

$153.9\ cm^{2}$

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:

$Area=\pi * radius^{2}$

Step one

Let

$\pi =3.14\\and\\r= 7 cm$

Step two

put the values into the equation

$Area=\pi * radius^{2} \\Area=3.14* (7 cm)^{2}\\ Area=3.14* 49\ cm^{2} \\Area=153.9\ cm^{2}$

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
