Question

imi puteti da formulele la sfera si con?va roooog

Answer 1

La sfera
Aria= $4 \pi * R^{2}$
Volumul =$\frac{ 4\pi* R^{3} }{3}$
La con
Aria laterala = $\pi*R*G$
Aria totala = $\pi R*(R+G)$
Volumul = $\frac{ \pi * R^{2} *h}{3}$

Answer 2

Aria sferei = $4 \pi r ^{2}$
Volumul sferei= $4 \pi r ^{2} /3$
Con:
Aria bazei=$\pi r^{2}$
Aria laterala=$\pi rG$
Aria totala=$\pi r(r+G)$
Volumul=$\pi r^{2} h /3$
