Answer:
The volume of the regular tetrahedron is 283.5 m³
Step-by-step explanation:
The formula of the volume of the regular tetrahedron is V =
A h, where
∵ The area of the base of a regular tetrahedron is 98.9 m²
∴ A = 98.9 m²
∵ The height of it is 8.6 m
∴ h = 8.6 m
→ Substitute them in the formula of the volume above
∵ V =
(98.9)(8.6)
∴ V = 283.5133333 m³
→ Round it to the nearest tenth of a cubic meters
∴ V = 283.5 m³
∴ The volume of the regular tetrahedron is 283.5 m³
there are a total of 32 students that don't like sandwiches
6 that don't like pie
so 6/32 = 0.1875 = 18.75% round to 18.8%
Answer is D
Maximum is when pi / 2t = 1 so that's 33-20 = 13 degrees
minimum when pi/2t = -1 - that gives -33-20 = -53 degrees
Its C
