Answer:
55 m²
Step-by-step explanation:
The arc length of a half-circle is πr, so the area of the curved surface is ...
A = πrl = π(2.5 m)(7 m) = 17.5π m² ≈ 55 m²
Step-by-step explanation:
Centre of circle(h,k)=(1,-4)
radius of the circle(r)=2
Equation of the circle is,
(x-h)^2+(y-k)^2=r^2
(x-1)^2+(y+4)^2=2^2
x^2-2x+1+y^2+8y+16=4
x^2+y^2-2x+8y+13=0 is the req.equation of the circle.
