Each revolution travels 2.8 m. In 15 revolutions is will travel 2.8 * 15 = 4.2 m. m/revolution * revolutions = m ... WebNov 23, 2024 · Let us write the circumference formula and then we will substitute the value of r (radius) in it. Circumference of circle formula = 2πr. C = 2 × π × 25. C = 2 × 3.14 × 25 = 157 units. Therefore, the circumference of a circle is 157 units. Given: diameter= 1.8 m. radius= 0.9m. Now, Circumference of circle =2πr = 2* 3.14 * 0.9 = 5.652 m
What is the circumference of a circle with radius 8 m?
WebThe radius, diameter, and circumference of a circle are all related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter. The value of π is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as ) and ... WebCircumference of base = 2πr. radius (r) = 1.5 m. Circumference of the base = 2(3.14)(1.5) = 9.42 m 2. So, circumference of the base is 9.42 m 2.
