Question

Two semicircles are attached to the sides of a rectangle as shown.
What is the area of this figure?
Use 3.14 to approximate pi.
Enter your answer in the box. Round only your final answer to the nearest whole number.

Answer 1

arae of rectangle =l×b
=18×8
= 144 ft
area of 2 hemisphere= area of circle
= πr²
= 3.14 × 4 ×4
= 50.24 ft
area if figure = 144+50.24
= 194.24
=194 ft

Answer 2

here figure=rectangle +2semi circles
area of figure =area of rectangle +area of 2semicircles
area.of rectangle =length *breadth
=18*8
=144

as we know that 2equal semicircle=1circle

area of2 semicircles =area.of a circle=pi r square
=3.14*4*4
=50.24
=50
area of total figure=144+50.24
=194.24
=194ft^2

hope helps
