Answer:
A =78.5
Step-by-step explanation:
We need the radius to find the area of a circle
r = d/2 = 10/2 =5
The area of a circle is given by
A = pi r^2
A = 3.14 (5)^2
A =3.14 (25)
A =78.5
I wrote the steps down, hopefully you understand them and the answer is on the lower right corner.
Answer:
15
Step-by-step explanation:
Angle 2 is 2x+10
angle 4 is 4x+80
and from the figure we can understand that when we add these 2 equations
We get
6x+ 90= 180
6x = 180 - 90= 90
6x= 90
x = 90 ÷ 6 = 15
answer = 15
Answer:
66
Step-by-step explanation:
180 - 105 = 75
75 + 39 = 114
180 - 114 = 66
Answer:1.515152
Step-by-step explanation:
1000/30 = 133.3 per min
133.3x60
=8000ft to miles
=1.515152 mph
