Well the formula is : b1+b2/2 (h)
so the height would be solved as :
13.5 = 3+6/2 (h)
13.5 = 9/2 (h)
h = (13.5)/(9/2)
h = (13.5) x (2/9) *reciprocal*
h = (27) / (9)
h = 3
Answer:
The volume of the solid is the volume of the prism minus the volume of the cylinder.
For the cylinder, diameter = d = 4 cm
radius = d/2 = (4 cm)/2 = 2 cm
V = volume of prism - volume of cylinder
The volume of a prism is length times width times height.
The volume of a cylinder is pi times the square of the radius times the height.
V = LWH - (pi)r^2h
V = 6 cm * 6 cm * 15 cm - (pi)(2 cm)^2(15 cm)
V = 540 cm^3 - 60pi cm^3
V = (540 - 60pi) cm^3
Answer:
10
Step-by-step explanation:
For this you just have to plug 2 into a and 4 into b. You come to this expression:
3(2) + 4
This gives you 10
Answer:
Area = 45 km
Step-by-step explanation:
The area of a parallelogram = base * height
It is given that:
Base = 6 km
Height = 9 km
When these values are substituted into the are equation, the result is:
Area = 6 * 9
Area = 45 km
Hope this helps :)
Answer:
g(3) = 8
Step-by-step explanation:
To evaluate g(3) substitute x = 3 into g(x)
g(3) = 2(3) + 2 = 6 + 2 = 8
