Answer:
47.515 cm²
In meter square= 4.7515 *10^-3 m²
Explanation:
The radius of a circle = 5.5 cm
In meter= 5.5*0.01
= 0.055 m
the circumference= 34.56 cm
in meters = 34.56 cm*0.01
= 0.3456 meters
the area= 95.03 cm²
in square meters =95.03*(0.01)²
in square meters= 9.503*10^-3 m²
. area under the curve at the right
= Area of semi circle
= Area of circle/2
= 95.03 /2
= 47.515 cm²
In meter square= 4.7515 *10^-3 m²
