Answer:
31.1666666667
Step-by-step explanation:
Caculator
Hmm
we see the one point is at (0,0), how nice of them
we can see esily that the width is 2 and height is 8
when rorated around the y axis, the radius is th ewidth
so the volume is that of a cylinder
V=hpir^2
h=8
r=2
pi=3.141592
V=8*3.141592*2^2
V=8*3.141592*4
V=32*3.141592
V=100.530944
round to tenth
V=100.5 cubic units
height=8 units
width=2 units
radius=2 units
cylinder
volume was 100.5 cubic units
Answer:
115
Step-by-step explanation:
PKL=180-JKP
= 180-65
=115°
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
the other asnwers dont make any sense. but just take my word for it.
