Sagot :
Step-by-step explanation:
TSA of cylinder = 2πr (h + r)
according to the question
height = radius
then,
TSA = 2πr (r + r)
2464=2 × 3.1415×r ×2r
2464/4 ×3.1415 = r×r
196.08 = r^2
r = 14.00
r = 1 4 cm
We know,
volume = 2πr ^2 ×h
=2×3.1415×14×14×14 (h=r)
=17240.552 cm^3
Answer:
8620.5 cm³
Step-by-step explanation:
h = r
SA = 2πrh + 2πr²
Since h = r, we can substitute h with r.
SA = 2πr² + 2πr² = 4πr²
4πr² = 2464 cm²
r = 14 cm
V = πr²h
r = h = 14 cm
V = π(14 cm)²(14 cm)
V = 8620.5 cm³
