Answer:
Minimum area is : 1 * 35 = 35
Maximum area is : 19 * 17 = 323
Step-by-step explanation:
The parameter (P) of rectangle is calculated using:
P = 2(a+b)
We are given that,
P = 72
=> 2(a+b) = 72
=> a+b = 36
In rectangle, the lengths of both sides are different and a whole number (as mentioned in question), Therefore, the length of smaller side a can be varied from <u>1 to 17.</u> Similarly, the length of larger side varies from 19 to 35.
The area can be easily calculated using a*b.
Minimum area is : 1 * 35 = 35
Maximum area is : 19 * 17 = 323
When a tangent (top line with the arrow) and a secant (other line) intersect, they form an angle (55°) equal to:
55° = ½ (the larger intercepted arc minus<span> the smaller intercepted arc)
</span>
<span>55° = ½ (170° -x°)
55° = 85° -</span><span>½ x
</span><span>½ x = 30°
x = 60°

Answer:
324.99 cm³
Step-by-step explanation:
Total volume - inside volume
[pi × (3+1)² × (13.5)] - [pi × 3² × (13.5-1)]
216pi - 112.5pi
110.5pi
103.5 × 3.14
324.99 cm³
