Pick a point inside the circle. It should look like this point is the center of the circle. Call this point D. Draw lines CD and BD
CD makes a right angle with AC
BD makes a right angle with AB
The central angle formed by The given information above is
<BDC = 360 - 90 - 90 - 40
<BDC = 140.
Answer The arc measurement of BC = 140

Given:
square based pyramid = 3.5 cm base
side length = 7 cm
Base Area = (3.5cm)² = 12.25cm²
Surface Area = Base Area + 2sl = 12.25cm² + (2 * 3.5cm* 7cm)
S.A = 12.25 cm² + 49 cm²
S.A = 61.25 cm²
