Answer: 168
Step-by-step explanation: 70/5=14. 14x7=98. 70+98=168.
The area of the sector will also be 70/360
Sector area = 70/360 • pir^2
= 7/36 • pi • 8^2
A= 112/9 • pi
A= 39.1 inch^2
The answer for angle b is: 25°
SA=201.7cm^2
I used the equation
SA=pi^1/3(6*V)^2/3 in case you have any more questions like this
Answer:
x ≤ 1
Step-by-step explanation:
8 + 4x
12
4x
12 - 8
4x ≥ 4
Dividing both sides by 4 gives;
x ≤ 1
