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:
If it's an addition problem then just add 3 cups
Step-by-step explanation:
There isn't too much context here buddy :p
Its easy you just have to do the pi formula
C.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 77, -77
