Answer:
[tex]43.96 cm^{2}[/tex]
Step-by-step explanation:
So we have the radius (r)
r = 7 cm
We have the area formula,
[tex]A=2\pi r[/tex]
Substitute,
[tex]A=2(3.14)(7)\\A=6.28(7)\\\\A=43.96 cm^{2}[/tex]
Answer:
The area is 0.015m²
Step-by-step explanation:
Step one
Given that the expression for area of the circle is A = π r²
Step two
Now our raduis r= 7cm - - - meter =7/100= 0.07
And Pi = 3.142
Step three
Substituting r in the formula for area we have
A= 3.142*(0.07)²
A=3.142*0.0049
A= 0.015m²
