In the diagram Shown a 2 foot wide flower border surrounds the heart shaped pond.What is the area of the border?
Dimas [21]
This figure is what we would call a composite figure. A composite figure is a shape that is made up of multiple other shapes. when looking at the pond and the border that surrounds it, we can see that this heart shape is made up of two semi circles and a square. To find the area of the border, we will use the area formulas for semi circles and for squares: 

Semi Circle Area Formula: \pi  r^{2} ÷ 2
Square Area Formula: length x width 

Pi = 3.14 
Radius = Half of the diameter, in this case 6 

After finding the area of each shape, we can subtract the 2 ft width to find the area of the flower bed border.

The circular opening of a vase has an inside diameter of 13.5 cm.
Sunny_sXe [5.5K]

Answer:

Area = 143cm^2

Step-by-step explanation:

Given

Shape: Opening of a circular vase

Diameter =13.5cm

\pi = 3.14

Required

Determine the area

This opening implies a circle; hence the area will be calculated using area of a circle.

Area = \pi r^2

Solve for radius (r)

r = \frac{d}{2}

r = \frac{13.5\ cm}{2}

r = 6.75\ cm

Substitute 6.75 for r in Area = \pi r^2

Area = 3.14 * 6.75^2

Area = 143.06625

Area = 143cm^2 --- Approximated
