According to this chart, the area of a circle with a diameter of <span>2.2 m is
area=(pi)(r)^2=</span><span><span>(pi)(d/2)^2</span>
= (pi)(2.2/2)^2
= 1.21 (pi) m^2</span>
area=(pi)(r)^2=</span><span><span>(pi)(d/2)^2</span>
= (pi)(2.2/2)^2
= 1.21 (pi) m^2</span>
Answer:
1.
a.) 24in
b.)75.36in
c.)452.16in
Step-by-step explanation:
1a. The radius is half of the diameter, so all you have to do is add 12 + 12 which is 24.
1b. the circumfrence of a circle is C (Circumfrence)= so replace radius for 12 and then do 3.14(pi) x 2 which will get you 6.28 times 6.28 by 12 and you will get 75.36.
1c. Area= so first do the radius by the second power, or
, susitute r for 12 and you will get 144, times 144 by pi and you will get 452.16in
