Elodia [21]

Answer:

43

Step-by-step explanation:

1 , 4 , 7 , 10

→ Find the difference between each term

4 - 1 = 3, 7 - 4 = 3 and 10 - 7 = 3

→ Put this into the nth term format

3n + x

→ Write the 3 times tables above the sequence and find what you need to take away from the times tables to get to the sequence

3 , 6 , 9 , 12

1 , 4 , 7 , 10

→ Minus 2

3n - 2

Very easy math question
charle [14.2K]

Answer:

C. 179 ft²

Step-by-step explanation:

Area of circular path or walkway

= π × (R + r) × width

Where

R= Outer radius

r = Inner Radius

Diameter = 16 feet

Width = 3 feet

Inner Radius = Diameter/2

= 16 feet/2 = 8 feet

Outer Radius = 8 + 3 = 11 ft

Hence:

= π × (11 + 8) × 3

= π × 19 × 3

= 179.07078125 ft²

Approximately = 179 ft²

The area of the circular walkway = 179ft²

Option C is correct.
