Answer:
s = 22°
Step-by-step explanation:
158° and u are supplementary angles ( straight angle )
u = 180° - 158° = 22°
s = u = 22° ( complementary angles )
Volume of the cone is 942 cm³
Step-by-step explanation:
- Step 1: Find the volume of the cone given base area = 78.5 cm² and height = 12 cm
Volume of the cone = Base area × Height
= 78.5 × 12 = 942 cm³
