Answer: Statements 2 and 3
Step-by-step explanation:
On a drawing scale;
1cm - 4m
4CM - 16M (MULTIPLYING BY 4)
6cm - 24m (multiplying by 6)
7cm - 28m (multiplying by 7)
8cm - 32m (multiplying by 8)
9CM - 36M (MULTIPLYING BY 9)
Find the change
the change is 63-21=42
42 degrees in 12 hours
we want to find xdegrees/1hour
42/12=3.5 degrees per hour
Answer:
33.49 cubic inches
Step-by-step explanation:
The answer for this is C.
Volume of cone = (pi/3)r^2h
Volume of hemisphere = (1/2) (4pi/3)r^3
we are given r=6/2=3cm, h(cone)=8 cm,
so total volume
=(pi/3)r^2h + (1/2)(4pi/3)r^3
=(pi/3)*3^2*8 + (1/2)(4pi/3)*3^3
=24pi + 18pi
=42pi cm^3
=131.9 cm^3 (approx.)
