Answer:
1: 64π
2: 49π and 153.86
Step-by-step explanation:
For the first one we know that it has a diameter of 16 which means it has a radius of 8 (half the diameter)
To find the area of a circle use the following formula
π*r² where r is the radius
This means that the first answer is π*8^2
which is 64π
For the second one it's the same deal but the radius is 7
so the answer is 49π
Triangle ABD and ADC are righttriangles so u can use the Pythagorean theorem/triples. the triples are 3/4/5 and 5/12/13. 12 is 4x3, and 15 is 5x3, so BD is 3x3, which is 9. AC is 13, as it is part of the Pythagorean’s triples
