The fourth identity is: 
Answer:
8 square units
Step-by-step explanation:
Area of a rectangle= lenght x width
locating the four points on a Cartesian plane
lenght = BC= AD = (0,4)->(4,4) = 4units
width = AB = CD = (0,2)-> (0,4) = 2units
Area of rectangle = 4units x 2units = 8 square units
Answer:
36 (Fill 3 in the blank)
Step-by-step explanation:
Given:
Volume of a cylinder = 324 π
Height = 9 cm
The formula to find the volume of a cylinder = Base area * height.
Base is a circle. So the area of a circle = πr^2
Volume of the cylindrical pillar = πr^2 h
324 π = πr^2 . 9
πr^2 = 324 π /9
πr^2 = 36 π
The area of the base = 36 π
Thank you.
