We will use the proper formula and solve.
-> A diameter of 48 / 2 = 24 feet as our radius
Area:
A = πr²
A = (3.14)(24)²
A = 1,808.64 ft²
The circle has an area of about 1,808.64 ft²
Circumference:
C = 2πr
C = 2(3.14)(24)
C = 150.72 ft
The circle has a circumference of about 150.72 ft
Do the ride over run method and you should be good
Answer:3.
Step-by-step explanation:
Given
Penguin dove to 130 feet below water surface
Then it swam 48 feet towards the water surface
So, penguin is 
below water surface
For water level penguin swam to 82 feet below it
Therefore 
represent the penguin swam to
Answer:
15
Step-by-step explanation:
Prime Numbers Check
15: 5 * 3
30: 2 * 3 * 5
75: 3 * 5 * 5
Both 3 and 5 are prime numbers present in all 3 greater numbers, then you multiply them
3*5 = 15
GCF is 15
