Answer:
Andre is taller.
Step-by-step explanation:
I assume Andre's height is 1.7 m.
Let's convert Andre's height to cm.
1 m = 100 cm
1.7 m = 1.7 * 1 m = 1.7 * 100 cm = 170 cm
Andre is 170 cm tall. Diego is 165 cm tall.
Since 170 cm > 165 cm, Andre is taller.
Answer:
the radius of the sphere is 12 cm.
Step-by-step explanation:
IN A CONE
vertical height (h) = 27 cm
radius (r) = 32 / 2 = 16 cm
Now the volume of cone is
= 1/3 *h*π*r²
= 1/3 * 27 *π *16²
= 2304π cm³
Also by the question the cone and the sphere have equal volumes so
volume of sphere = volume of cone
= 2304 π cm³
OR, 4/3 πr³ = 2304 π
4/3 * r³ = 2304
r³ = 2304 * 3 / 4
r³ = 1728
r = ∛1728
r = 12 cm
hope it helps :)
