Let the radius of the circle to be as r so , B / C , ------ The area of a circle = 22 / 7 × r2 -------------------------------- => 22 / 7 × r2 = 154m2 ---------------- => r2 = 154 ÷ 22 / 7 --------------------- = 154 / 1 × 7 / 22 = 7 / 1 × 7 / 1--- = 7 × 7 = 49 --------------------------------- therefore the radius of the circle = 49 m -------------------- So, B/C ----------------------------------------------------------------------- The perimeter of the circle = 2 × 22 / 7 × 49 ---- = 2 × 22 × 7 ----------- = 308 m ----------------

Yogita Ingle 3 days, 18 hours ago

A linear equation is any equation that can be written in the form

ax + b = 0

where a and b are real numbers and x is a variable. This form is sometimes called the standard form of a linear equation. Note that most linear equations will not start off in this form. Also, the variable may or may not be an x so don’t get too locked into always seeing an x there.
