Question

find area of unshaded part​

Answer 1

48cm² - 3.14 × 1.5² - 3.14×1² - 3.14×1² cm² = 34.655 cm²

Step-by-step explanation:

area of rectangle - area of three circles

lb - πR² - πr² - πr²

Answer 2

Answer:

The answer is (A) 28.375 m².

Step-by-step explanation:

If the length of a rectangle is 'a' units and the breadth the rectangle is 'b' units then , the area of the rectangle will be ( a × b ) square units.

If the radius of a circle is 'r' units then the area of the circle will be πr² square units.

In this case , a = 8 meters and b = 6 meters

then , the area of the given rectangle is ( a × b ) = ( 8 × 6 ) = 48 m²

Then , the area of the shaded region is ,

4{ π(2)²/4} + π(3/2)²

= π{(2)² + (1.5)² } = 3.14{ 4 + 2.25 } = 3.14 × 6.25 = 19.625 m²

∴ The area of the unshaded region is ( 48 - 19.625 ) = 28.375 m²
