However, a yet lower flux value with a further outer boundary of the HZ may be derived from the evidence for an intra-glacial lake in Mars’s south pole 11. WebbThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps! ( 9 votes) Flag

WebbThe length of the boundary of a circle is the circle’s circumference. Hence, let’s find the circumference first. Given, diameter (d) = 15 cm Circumference (C) = πd = 3.14 × 15 cm … WebbThe outer boundary, of this figure, is made up of semicircles. Diameter of each semicircle is 14 cm. We know that: Circumference of the circle = πd Circumference of the semicircle = `1/2`πd = `1/2 xx 22/7` × 14 cm = 22 cm. Circumference of each of the semicircles is 22 cm. Therefore, perimeter of the given figure = 4 × 22 cm = 88 cm.
