The area of the 5 metre target is 25*pi metres2 whereas the bigger target has an area of 49*pi metres2.
The difference is 24*pi = 75.4 sq metres.
890.19m3
It is: 2*pi*100 meters

User an oil tanker spills 100,000 cubit meteres (m^3) of oil, which forms a slick that spreads on the water surface in a shape best modeled by a circular disc of radius r meters and thkciness h meters. The radius of the circular disc is increasing at a rate or 3 m/min. At t= T, the area of the "circular" slick reaches 100pi m^2. (C) find the rate of chnage of the area of the slick with respect to its thcokness
How much fencing is required to enclose a circular garden with a radius of 14 meters? (Use 3.14 for π) _
890.19m3
It is: 2*pi*100 meters
A cylinder with a radius of 3 meters and a height of 5 meters has a volume of 141.37 cubic meters.
The volume is 47.12 cubic meters.
The volume is 141.37 cubic meters.

Approx 25.13 metres.
The distance covered by the cyclist when riding halfway around a circular track with a radius of 140 meters is equal to the circumference of the circle, which is 2 * π * radius. Therefore, the distance covered would be 2 * π * 140 = 880 meters.
The radius is the distance between the centre of a circular arc and a point on the arc.
In circular motion, velocity is directly proportional to the radius and angular velocity (omega). This means that as the radius or angular velocity increases, the velocity of the object in circular motion also increases.

Circumference: 2*pi*1.35 = 8.482 meters to 3 decimal places
