Answer:diameter=9.92m

Step-by-step explanation:

Area=77.28

π=3.14

Area=π x (d/2)^2

77.28=3.14 x (d/2)^2

Divide both sides by 3.14

77.28/3.14=(3.14x(d/2)^2)/3.14

24.6=(d/2)^2

Take them square root of both sides we get

d/2=√(24.6)

d/2=4.96

d=4.96 x 2

d=9.92

<em><u>142.34 divide by 24 will give you the answer of 593.083 ----> </u></em>

<em><u>24 x 5 will equal 120 which is close to 142 then subtract 120 by 142 which will give you 22 then bring down the 3 and you will have 223 which 24 x 9 will give you 216 then subtract 223 -216 which gives you 74 then 24 x 3 = 72 then you add a decimal then a zero which is 20 then add another zero which is 200 then multiply 24 by 8 which is 192 and then subtract 200 by 192 and get 72 and then your answer will keep on going</u></em>.
