Answer:
12566.4 mm²
Step-by-step explanation:
The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.
TSA = Total Surface Area
CSA = Curved Surface Area
TSA of open cylinder = CSA of cylinder + area of base or top
= 2πrh + πr²
= πr(2h + r)
From the above question:
r = 50mm
h = 15mm
Hence,
= π × 50 (2 × 15 + 50)
= π × 50 (30 + 50)
= π × 50(80)
= π × 4000
= 12566.370614mm²
Approximately = 12566.4 mm²
The Surface Area of the petri dish with no lid = 12566.4 mm²
Answer:
The answer to your question is height = 12 mm
Step-by-step explanation:
Data
l = w = 9 mm
V = 324 mm³
h = ?
Formula
V = 
Solve for h
3V = Ab h
3V / Ab = h or h = 3V / Ab
Find the area of the base
Ab = l x w
= 9 x 9
= 81 mm²
Substitution
h = 
Simplification
h = 
Result
h = 12 mm
