Question

find the radious and perimeter of asem circle area 77cm square

Answer 1

Answer:

The radious is 12 and perimeter is 10

Answer 2

Answer:

area of circle = 77 cm^2

=πr^2 = 77

= (22/7) x r^2 = 77

= r^2 = (77 x 7) / 22

= r^2 = 49/2

= r = 7/√2 cm

perimeter = 2πr = 2 x 22/7 x 7/√2

= 22√2 cm

Step-by-step explanation:

Radius of the circle is 7/√2 and perimeter of the circle is 22√2 cm.

The area of the circle is given as 77 cm².

Now area of circle is πr².

πr² = 77

r = 7/√2 cm.

Now perimeter of the circle is the same as circumference of the circle.

Circumference of the circle = 2πr = 2×22/7×7/√2 = 22√2 cm.

Perimeter of the circle is 22√2 cm.
