Step-by-step explanation:
The area of the shaded portion is the area of the outer circle subtract the area of the inner circle
area of larger circle = πr² ← r is the radius = 11
area = π × 11² = 121π
area of smaller circle = πr² ← r = 9
area = π × 9² = 81π
-----------------------------------------
shaded area = 121π - 81π = 40π m² ≈ 126 m²
Answer:
$10356,22
Step-by-step explanation:
15500*(1-(6,5/100))^6=10356,22
X= 1,-3 If you factor equation you get x-1=0 and x+3=0
Find a common denominator between the two (this case it would be 18) and bring the fractions up, so 10/9 would be 20/18, and 3/2 would be 27/18. Then, multiply across, and simplify to lowest terms.
96 people are attending the concert.
Step-by-step explanation:
Given,
Number of children at concert = 12
This represents 12.5% of the people attending concert.
Let,
p be the total people attending concert.
12.5% of p = 12

Dividing both sides by 0.125

96 people are attending the concert.
