WebJul 20, 2024 · a → r ( t) = − r ω 2 ( t) r ^ ( t) uniform circular motion . Because the speed v = r ω is constant, the amount of time that the object takes to complete one circular orbit of radius r is also constant. This time interval, T , is called the period. In one period the object travels a distance s = vT equal to the circumference, s = 2 π r; thus WebNote that the radius is simply half the diameter. The formula for the volume of a cylinder is: V = Π x r^2 x h. "Volume equals pi times radius squared times height." Now you can solve for the radius: V = Π x r^2 x h <-- Divide both sides by Π x h to get: V / (Π x h) = r^2 <-- Square root both sides to get: WebFeb 14, 2024 · Use the Distance Formula to find the distance between the points \((10,−4)\) and \((−1,5)\).
