Answer 1

Answer:

616 square centimeters

Step-by-step explanation:

Diameter of circle = 28 centimeters

π = 22/7

Area of a circle, A = π $\frac{D^{2} }{4}$

A =  $\frac{22}{7}$ * $\frac{28^{2} }{4}$

A =  $\frac{22}{7^{1} }$ * $\frac{(4 * 7)^{2} }{4}$

A =  $\frac{22}{7^{1} }$ *  $\frac{4^{2} *7^{2} }{4}$

A = 22 * 28

A = 616 square centimeters

Answer 2

Answer:

616 cm²

Step-by-step explanation:

To find the area of a circle you use the formula A = π · r²

So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.

196 × (22/7) = 616
