Web3 × 8 = 24The approximate circumference of the coin is 24 cm. This is the radius. The circumference of every circle is a little more than 3 times the length of its diameter. Try again. You may have multiplied the diameter by the radius. The circumference of every circle is a little more than 3 times the length of its diameter. Try again. WebTo get the radius, you just divide the diameter in two, because the diameter is all the way across the coin and the radius is the distance from the center of the coin to the outside. …

WebFeb 3, 2015 · 1 A coin of radius 2 is touching a coin of radius 9. The point of tangency is marked as A on the smaller coin and B on the larger coin. The smaller coin is then rotated around the larger coin, without slipping, until the two coins come into contact again at points A and B. Find the distance traveled by the center of the smaller circle. WebThe number of circles of radius which can be fit around a central circle of radius depends only on the fraction . This is because all of the circles can be scaled in size and this will not impact the fraction or the number of circles of radius which fit around the circle of radius . To fit more circles, we need a larger value for .
WebDec 2, 2024 · Therefore, Volume of one coin = pi. (1/4r)^2.h = 1/16.pi.r^2.h. Thus, bigger coin is melted into 16 such coins. Since, value is inversely proportional to radius. And radius is reduced by 1/4, value will be increased by 4 times for one coin ie 4V1. Since, there are 16 such coins, value for 16 coins would be 16*4*V1 =64V1.
