Answer :-
R= 7
Explanation:-
The diameter is 2 times the radius
So the radius is 14/2 =7
Find another point (-2, -2)
Find the slope (-2-1)/(-2+3)
Insert into formula y-y1=m(x-x1)
y-1=(-3/5)(x+3)
Answer:
16+32÷4+(10-6)2=16+8+8=32
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
