The area of the shaded face of the cylinder is 1,520 mm².
<h3>How to find the area of the shaded area?</h3>
We can see that the shaded area of the cylinder is circular in shape.
This means that we can find the area of the shaded area by finding the area of the circle.
The radius of the circle is given as 22 mm.
The formula for finding the area of a circle is given as:
<em>Area = πr²</em>
= 3.14 × 22 × 22
= 1,519.76
≈ 1520 mm²
Therefore, we have found the area of the shaded face of the cylinder to be 1,520 mm².

Answer: 0.81859
Step-by-step explanation:
Using the formula ;
Z = 
where u = mean
Therefore the probability that a student will finish the test between 40 and 70 will be :
P ( 40≤X≤70 ) = P(X≤70) - P(X≤40)
P ( 60-40/10) , P( 60 - 70 / 10)
= 2 , -1
= P (Z ≤ 2) - P( Z ≤ -1 )
From normal table , we have
0.97725 - 0.15866
Therefore the probability that a student will finish the test between 40 and 70 minutes = 0.81859
Answer:
p = 2/15
Step-by-step explanation:
p = (2/5)*(1/3)
p = 2/15
To solve for the mass of a substance is to simply get the
product of volume and density, that is:
mass = density * volume
So calculating for mass:
mass = (2.76 g / cm^3) * 6 cm^3
<span>mass = 16.56 g</span>
Answer:
y(t)''=3y(t)^2-(s2+13)
Step-by-step explanation:d[y(t)]/dt is the same thing as y'(t). Thus:
d[y'(t)]=y''(t); d[y(t)^3]=3.y(t)^(3-1)=3y(t)^2; and d[k.y(t)] is k, where k is a variable or constant that independs on y.
