3x = 32 - 11
3x = 21
x = 21/3
x = 7

19. A spherical balloon has a circumference of 19cm. what is the approximate surface area of the balloon to the nearest square c

Tamiku [17]

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>
