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
Depending on if you're solving for X or Y:
X less than or equal to 4y/3 -5
Y greater than or equal to 3x/4+15/4
B because if jennifer stands on a sidewalk with her bicycle u have to divide that by 7 multiply by 8
Answer:
The length of AM is 26.50 units.
Step-by-step explanation:
Given information: AB = BC, BM = MC
, AC = 40, ∠BAC = 42º.
Since two sides of triangle are equal, therefore the triangle ABC is an isosceles triangle.
The corresponding angles of congruents sides are always equal. So angle C is 42º.
According to the angle sum property the sum of interior angles is 180º.
Law of Sine
Therefore the length of AB and BC is 26.91.
Since M is midpoint of BC, so
Use Law of Cosine in triangle ABM to find the value of AM.
Therefore the length of AM is 26.50 units.
