StartFraction 3 pi Over 4 EndFraction radians
Step-by-step explanation:
Pi radians is equal to 180°
Given the minor arc angles as 135°, change this value to pi radians
180° =π radians
135° = ?
Cross multiply
135° * π radians / 180°
=135/180 * π radians
=3 π/4 radians

Step-by-step explanation
Pi times radius to the power of 2 times height
(7t-2) - (-3t+1) = -3*(1-3t)
First distribute:
7t-2+3t-1 = -3+9t
Now get all the terms with 't' on the same side by subtracting/adding:
7t+3t-9t = -3+2+1
Combine the terms:
1t=0
t=0
Check:
Plug in 0 for t and see if both sides of the equation come out the same:
Does (7(0)-2) - (-3(0)+1) = -3(1-3(0)) ?
(-2) - (1) = -3(1) ?
-3 = -3 ?
Yes! It works, so t=0!
Answer:
2%
Step-by-step explanation:
True measurements = 400 meters
Observed measurements = 392 meters
% error = change in measurements / true measurements × 100/1
= (400 - 392) / 400 × 100
= 8/400 × 100
= 0.02 × 100
= 2%
Percentage error of Beth measurements = 2%
