where, radius = 3cm

Surface area = 4πr²

= 4 × 3.14 × 3²

= 4 × 3.14 × 9

= 113.04

= 113.0cm²

What is the radius of a circle whose equation is (x + 5)2 + (y - 3)2 = 42?
777dan777 [17]

Answer:

x=−y+19

Step-by-step explanation:

(x+5)(2)+(y−3)(2)=42

Step 1: Add -2y to both sides.

2x+2y+4+−2y=42+−2y

2x+4=−2y+42

Step 2: Add -4 to both sides.

2x+4+−4=−2y+42+−4

2x=−2y+38

Step 3: Divide both sides by 2.

2x

2

=

−2y+38

2

x=−y+19
