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

Hey there!
Make the 2% to a decimal which is .02 and multiply it by 57 to find the sales tax
.02*57= 11.4
So 11.4 is the sales tax
So add 11.4 to 57 and you get
$68.40 is the total cost
Hope this helps!
Answer:
x = -10
Step-by-step explanation:
-4x - 18= 22
-4x = 22 + 18
-4x = 40
x = 40/-4
x = -10
