Round to the nearest tenth. Use 3.14 or 22/7 for π.​

Note: Consider we need to find the circumference and area of the given circle.

Given:

A circle with radius 7.1 m.

To find:

The circumference and area of the given circle.

Solution:

Circumference of a circle is:

Putting , we get

Therefore, the circumference of the circle is 44.6 m.

The area of the circle is:

Putting , we get

Therefore, the area of the circle is 158.3 sq. m.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
