formula for area of circle, A = pi*r²
1519.76 m² = pi*r²
r² = 1519.76/pi = 483.7546 m
r = square root of 483.7546 = 21.99 m
radius of circle is approximately 22.0 m.

Area = pi r^2
1519.76 = pi r^2
r^2 = 1519.76/pi
r = 21.98
= 22m

π.r² = 1519.76
r = √ (1519.76 / π ) m
r = 22 m (to nearest whole number)
OPTION 1.
