WebYou should think about the "before" quantity (even though it is not given in the question) Find the percentage change as a multiplier, p (the decimal equivalent of a percentage change) a percentage increase of 4% means p = 1 + 0.04 = 1.04. a percentage decrease of 5% means p = 1 - 0.05 = 0.95. Use "before" × p = "after" to write an equation. WebArea = 32π cm2. The perimeter of the semicircle is made up of both the arc of the circle (half of the circumference) and the diameter of the semicircle. Find the full length of the circumference of the circle using the formula (or ). Substitute the radius = 8 cm into the formula. Again, leave your answer in terms of .

WebThe first circle theorem we’re going to use here is: Rule 3, the angle at the centre is twice the angle at the circumference. The angle at the centre is 126\degree 126°, so; \angle BAD = 126\degree \div 2 = 63\degree ∠B AD = 126° ÷ 2 = 63°. We now know two out of the four angles inside ABCD AB C D.
