Answer:
πr²
Step-by-step explanation:
The surface area of a circle is πr²
Pie is 22/7 or 3.14
While the radius of a circle is any line from the centre of a circle to any part of the circumference of the circle. A diameter is any line that cuts the circle into two equal halves, cutting the circle from the centre.
To get the surface area of a circle, you draw a line from the centre of the circle, and then touch any part of the circumference of the circle. Then you measure the line, that's the radius.
If for instance, the radius gives 7cm, you find the Square, And then multiply it with pie.
22/7 X 7 ²
22/7 X 7 X 7
22 X 7
154cm²
Answer:
Subtract ax from both sides. ax + by − ax = c − ax.
Simplify. by = c − ax.
Divide both sides by b ; b ≠ 0. by b = c b − ax b ; b ≠ 0.
Simplify. y = c − ax b ; b ≠ 0.
