In the diagram, the lenght of segment BC is 23 units. What is the lenght of segment DC?
2 answers:
The length of the segment is 33 units
AB = BC
2x + 7 = 23
2x = 16
x =8
AD = 4x + 1 = 4(8) + 1 =33
but
AD = DC
so
DC = 33
answer
D. 33 units

Answer:
The radius 10 cm
Step-by-step explanation:
∵ The volume of the cone = 1/3 πr²h
∵ v = 1256 cm³
∵ h = 12 cm
∴ 1256 = 1/3 π (12) r²
∴ r² = 1256 × 3/12π = 100 cm
∴ r = √100 = 10 cm
