Question

Find the area of the smallest square that can be circumscribe a circle of area of area 154 cm square

Answer 1

Answer:

We know

Area of circle = 154 cm²

we know, area of circle of radius R is given by,

A = πR²

so, πR² = 154

or, 22/7 × R² = 154

or, R² = 154 × 7/22 = 7 × 7

hence, R = 7 cm

we have to find area of smallest square that can be circumscribed the given circle.

so, diagonal of square = diameter of circle

ROOT 2 × side length of square = 2 × R

side length of square = 2 × 7/√2 = 7√2 cm

hence , area of square = (7 ROOT 2)² = 98cm²
