WebApr 11, 2024 · AB is the diameter of a circle with centre O. ∠CAB = 42° and ∠ABD = 57° Concept used: The diameter of a circle makes an angle of 90 degree on the circumference. The opposite angles of a cyclic quadrilateral are supplementary which means that the sum of either pair of opposite angles is equal to 180 degrees. Calculation: WebAug 25, 2024 · So, the area of a circle is pi*r^2. Let's start with that: A = πr^2. The question tells you that the circle's radius, AKA the value r, is 4. So let's plug that in right now: A = π4^2. A = π16. Next, we want to understand what fraction of the circle's total area is represented by the shaded portion. WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different … In geometry, the circumference (from Latin circumferences, meaning "carrying … davy crockett street temple tx
