Circumference = 2 · π · r or π · d
Radius = 7.8
7.8 × 2 = 15.6
15.6 × 3.14(π) = 48.984
Circumference = 48.984 rounded = 49
Area = π · r²
Radius = 7.8
7.8 × 7.8 = 60.84
60.84 × 3.14(π) = 191.0376
Area = 191.0376 rounded = 191
Hope this helped☺☺

Answer:
For the y=2x+11 the answer would be x=1/2y+-11/2
Step-by-step equation:
Step 1: Flip the equation.
2x+11=y
Step 2: Add -11 to both sides.
2x+11+-11=y+-11
2x=y-11
Step 3: Divide both sides by 2.
2x/2=y-11/2
<u>x=1/2y+-11/2</u>
