Answer:
Step-by-step explanation:
Given
Total = 900
Singing = 600
Dancing = 500
None = 125
Required
Determine the number of students that participate in both
Representing; Singing with S, Dancing with D, Both singing and dancing with B and None with N;
In Set Notation;
Substitute 900 for Total, 600 for S, 500 for D and 125 for N

Collect Like Terms
Collect Like Terms
Multiply both sides by -1
Reorder
<em>Hence, the number of students that do not participate in both is 325</em>
Answer:
V=125π in³
S= 100π in²
Step-by-step explanation:
From the question statement , we observe that
r= 5 inches h= 5 inches
V=πr²h
putting the values of radius and height in above formula,
V=π(5)²(5)
V=125π in³
Now, we have to find surface area,
S=2πr²+2πrh
S=2π(5)²+2π(5)(5)
S=50π+50π
S=100π in²
Pythagorean theorem.....a^2 + b^2 = c^2....where a and b are the legs and c is the hypotenuse
a^2 + 35^2 = 37^2 <===
