NCERT MCQ Questions for Class 9 Science Chapter 1 Matter in Our Surroundings. If the radius of the circle is 1.Matter in Our Surroundings MCQ Questions Class 9 Science Chapter 1 Since we know the area, all we need to do is divide the area by \pi, and square root the answer. If we now take the square root of both sides, we have a formula for the radius: However, we know the area and want a formula for the radius, so we will need to rearrange this formula. The formula for the area of a circle is \pi r². In this question, we therefore need to apply some basic knowledge about the circle areas. We now know that the area of the circular face on which the cylinder is resting has an area of 6 m ^2, and from this information we need to work out the diameter of the cylinder / circle. \textīy substituting the values for the force and the pressure into the formula above, we can calculate the area as follows: Since we know both the force and the pressure, the only thing we are able to calculate at this stage is the area of the circular cylinder face. We have been given the pressure as well as the weight (force) of the cylinder. This may seem like an impossible question without sufficient information to go by at first glance. ![]()
