P=2w+2l
74=2(16)+2l
74=32+2l
42=2l
21=l

Answer:
b = 58
Step-by-step explanation:
Complementary angles add to 90 degrees.
a+b = 90
32+b = 90
Subtract 32 from each side
32+b-32 = 90-32
b = 58
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
