Suface area= 2πrh+2πr²
= 2×3.14×2×15+2×3.14×2²
= 6.28×2×15+6.28×4
=188.4+25.12
=213.52
so Surface area=213.52cm
Answer:
3 cm
Step-by-step explanation:
First, find the volume of the cone.
V = 
r²h
V =
(3.14)(9)(12)
V = 113.04
This means the sphere is also 113.04
Use the formula V = 
r³
113.04 =
(3.14)r³
113.04 = 4.19r³
26.98 = r³
3 ≈ r

Answer:
Below.
Step-by-step explanation:
-5/8 * 1/3 = -5/24
-5/12 * 1/2 = -5/24
-5/6 * 1/4 = -5/24.
