<span>r means radius so it can't be negative.
<=>
A = 4 pi r²
r = sqr (A / 4pi)

Answer:
∠ R = 75°
Step-by-step explanation:
you are correct with answers to a, b, c
d
the sum of the 3 angles in Δ QRS = 180° , that is
∠ Q +∠ R + ∠ S = 180° , so
55° + ∠ R + 50° = 180°
∠ R + 105° = 180° ( subtract 105° from both sides )
∠ R = 75°
An algebraic expression consists of one or more numbers and variables, for 1/8y it will be y+1/8
Hey there,
100% = 38.4
1% = 38.4 / 100
= 0.384
32.5% = 0.384 x 32.5
= 12.48
Thus, 12.48 is 32.5% of 38.4
Hope this helps :))

Answer:
X=-2
Step-by-step explanation:
Consolidate like figures 2/3x-2x=8
Divide 2x by one 2/3x-2/1x=8
Find common denominator 2/3x-6/3x=8
Subtract fractions -4x=8
Divide 8 by negative 4x- 8/-4x
Answer is x=-2
