Question

Ребят помогите пж, если что 22/7 это дробь! Найдите длину окружности если площадь круга, ограниченного этой окружностью, если её радиус равен 7 см. Считайте это П=22/7

Answer 1

С=2πr=2*22/7*7=44См
s=πR²=22/7*7²=22/7*49=154СМ²

Answer 2

Finding the Length of a Circle with a Given Radius

To find the length of a circle, also known as the circumference, we can use the formula:

Circumference = 2 * π * radius

Given that the radius of the circle is 7 cm and the value of π is approximated as 22/7, we can substitute these values into the formula to find the circumference.

Circumference = 2 * (22/7) * 7

Simplifying the expression:

Circumference = (2 * 22 * 7) / 7

Circumference = 44 cm

Therefore, the length of the circle, or the circumference, is 44 cm.
