The main formula of a spherical surface area is SA= 4 x Pi x r²
the circumference is C= 19cm =2 Pi r, so r = C/ 2Pi = 19 / 6.28 =3.02cm
so the surface area can be found by computing
SA= 4x 3.14x 3.02² =114.5, the nearest square centimeter is <span>A) 114 cm^2</span>
Answer:
Step-by-step explanation:
this is simplify
11 is the biggest and the 22
The diameter is two times the radius.
2 * 1 = 2
So the diameter is 2 yards.
