Answer:
32 square feet
Explanation:
Square feet for sand box after flower bed is installed = Area of sandbox - Area of Flower bed.
Area of sandbox
The sandbox is a rectangle so we can find the area simply by multiplying the length by the width.
given length = 10 ft and given width = 6ft
so area = 10 × 6 = 60ft²
Area of flowerbed.
The flower bed is a circle
The area of a circle can be calculated using the formula A = πr²
where r = radius.
The width of the sandbox is the same length as the diameter of the flower bed so diameter = 6ft
To convert diameter to radius we simply divide by 2
So radius = 6/2 = 3ft
So we have A = πr²
==> plug in r = 3
A = π(3)²
==> evaluate exponent
A = π9
==> multiply π and 9
A = 28 ( rounded )
Area for sand.
again area for sand = area of sandbox - area of flower bed
Area of sandbox = 60
Area of flower bed = 28
Area for sand = 60 - 28 = 32
