Find the area of a circle with diameter 18 ft
2 answers:
Hello :
the area is : A=<span>πr²
</span> π ≃ 3.14 r : <span>ridus
</span> <span>diameter = 2 r
</span>r = 18/2= 9 ft
A=3.14×9² = 254.34 ft²
Formula of the Area of a circle: π.R²
Diameter =18 ft so R ,te radius = 9ft
Hence area of this circle =π.(9)²= 81π ft² OR 254.47 ft²

Answer:
d. -4
Step-by-step explanation:
- 4p – 12 = 8 + 4p + 5p
- 4p – 12 = 8 + 9p
- 4p – 9p = 8 + 12
- – 5p = 20
- p = 20 ÷ (– 5)
- p = – 4
