Answer:
50.29 in^2
Step-by-step explanation:
From the circumference we need to find the radius.
Since C = 2*pi*r, r = C / (2*pi).
Here, with C = 25 1/7 in, r = (25 1/7 in) / [ 2(22/7) ], or r = 4 in
The area of the cake is A = pi*r^2, or (here) A = (22/7)(4 in)^2 = 50.29 in^2
Translation is the sliding of one triangle over another
Answer:
(-∞, 5 U 7 , ∞)
Step-by-step explanation:
Given the inequality expressions
d – 4 > 3 or d – 4 < 1
For d - 4 > 3
Add 4 to both sides
d-4 + 4 > 3 + 4
d > 7
7 < d
this means that d is greater than 7,
(7 , ∞)
For d - 4 < 1
Add 4 to both sides
d - 4 + 4 < 1 + 4
d < 5
This means d is less than 5
(-∞, 5)
The required solution is (-∞, 5 U 7 , ∞)
