A = pi (r)^2
so with 222r
circle changes by a factor of 222^2
Answer:
-2 4/7
Step-by-step explanation:
−3 2/7 − (−5/7)
Subtracting a negative is like adding
−3 2/7 + (5/7)
Since the signs are difference we subtract and take the sign of the larger number
3 2/7 - 5/7
Borrow from the whole number
2+ 7/7 + 2/7 - 5/7
2 9/7 - 5/7
2 4/7
The sign of the larger number is negative so add the negative sign
- 2 4/7

a = 180° -114°
a = 66°
Answer:
1.6 =x
Step-by-step explanation:
tan theta = opposite side/ adjacent
tan 37 = x /2.1
Multiply each side 2.1
2.1 tan 37 = x/2.1 * 2.1
2.1 tan 37 = x
1.582463505 =x
To the nearest tenth
1.6 =x
