What is risk assessment?
• systematic process for identifying
hazards and evaluating the risks they
pose
• allows to identify potential hazards
before they become problems
• enables proactive measure to mitigate
risks and prevent harm
objectives 1. Identify the center and radius of a circle
given its standard equation
2. Graph circles in CCP given its standard
equation; write the equation of the circle
in standard form given its graph
3. Apply graphs of circles in real-life
situations like typhoon tracking and risk
assessment
activity 1
TOTGA
(presidentiables edition)
TOTGA
• there will be 5 questions
focusing on the center and radius
of the given circles
• raise your showcard/s for your
responses

activity 3
alerto
(risk assessment task)
• each group will be given 15 minutes
to solve and prepare their output
• plot the circles in the CCP, write
their equations in standard form

1. Typhoon 'Auring' (local name 'Kiko') is currently a Severe Tropical
Storm located approximately 300km East of Baler Aurora (8, 8). It is
moving Southwest at 15 kph and is expected to make landfall over
Northern Samar within the next 24 hours. Heavy rainfall and strong
winds are anticipated across the Bicol Region and Eastern Visayas,
with potential for storm surges along the coast.
Below is the typhoon track of its center and due to cone of uncertainty,
