IN DONE VIVO THERE IS A SPHERE THAT OBSTACULATES THE PASSAGE IN THE ENTRANCE TO BE ABLE TO CUT AND REMOVE IT, YOU MUST FIND THE VOLUME OF THE SPHERE MEASURING 18 CM IN DIAMETER
SOLUTION
Volume = 4 / 3π · r³
Where:
π: is a constant with a numerical value 3.1416 ...
r: is the radius of the sphere.
The radius is half the diameter:
radius = diameter / 2
radius = 18/2 cm
radius = 9 cm
The volume of the sphere is then:
Volume = 4 / 3π · (9 cm) ³
Volume = 4 / 3π81cm³
Volume = 108π cm³
Volume = 339.30 cm³}
answer
el volumen de la esfera es: 339.30 cm³ por lo tanto se debe cortar a esta medidapara poderla retirar
