Answer:
There is a circle with a diameter[d] of 2.
Step-by-step explanation:
the Radius=diameter /2=2/2=1 units
now
circumference=2πr=2×π×1=6.29=6 units
area=πr²=3.14 unit²
The surface area formula for any sphere is 4(pi)(radius)^2
The radius is half of the diameter.
18.6 / 2 = 9.3
So, plug into the formula and solve.
4(3.14)(9.3)^2 = 1086.3 mm^2
