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:
2/10
Step-by-step explanation:
0.20 = 20/100
20/100 = 2/10
The answer is 128 pi in^3. You have to multiply 4x4, then multiply that by 8 to get 128.
