Question

Find the circumference and the area of a circle with radius of 9 yd use the value 3.14 pie and do not round your answers be sure too include the correct units in your answers

Answer 1

You know that circumference is 2$\pi$r

Therefore, the equation becomes; 
2(pi)(9)=18(3.14)
=56.52 yards

The area equation is (pi)(r)²
=(3.14)(9)²
=(3.14)(81)
=254.34 yd²

Hope I helped :) 

Answer 2

The circumference of the circle will be 556.52 yards and the area of the circle will be $A=254.34 \ \ Yd^2$

What is area of circle?

Area of a circle is the region occupied by the circle in a two-dimensional plane.You know that circumference is

$C=2\pi r$

Therefore, the equation becomes;

$2(\pi)(9)=18(3.14)$

$C=56.52 yards$

The area equation is  

$A=\pi r^2$

$A=(3.14)(9)^2$

$A=(3.14)(81)$

$A=254.34 \ yd^2$

hence the circumference of the circle will be 556.52 yards and the area of the circle will be $A=254.34 \ \ Yd^2$
