We first get rid of the fraction by multiplying both sides by 10
this gives us: -70+10x=x-160
subtract x from both sides
this gives us: =-70+9x=-160
add 70 to both sides
this gives us 9x=-90
divide both sides by 9
this gives us x=-10
Answer:
<h3>Area of a circle in terms of radius:</h3>
Area = π·r^2 = 3.14·9.5^2 = 283.5 square meters(*)
Area of a circle in terms of diameter:
Area = π·(d/2)^2 = 3.14·(19/2)^2 = 3.14·(9.5)^2 = 283.5 square meters(*)
Area of a circle in terms of circumference:
Area = C^2/4π = 59.69^2/4π = 3562.9/(4·3.14) = 3562.9/12.56 = 283.5 square meters(*)
(*) 283.52873698648 meters, exactly or limited to the precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
