1. What is the area of the shaded portion in the figure?
Answers
Answer:
for this
we have to subtract area of circle from area of rectangle.
Step-by-step explanation:
area of rectangle= L×b
= 10×6 m sq. = 60 m sq.
now, for finding area of circle that is πr²
we need to find radius
breadth of rectangle= diameter of circle= 6m { as shown in figure}
and radius = diameter÷ 2= 6÷2 = 3m
now area of circle= πr²
= 22/7 × 3^2
= 22/7 × 9
=28.26 m^2
therefore, area of shaded region,
= area of rectangle - area of circle
= 60 - 28.26
= 31.74 m ^2
Answer:
Area of Shaded Region: 32m^2
Step-by-step explanation:
Area of Rectangle = length * width : l*w
Area of circle = pi* radius squared: pi*r^2
Area of Shaded Region = Area of Rectangle - Area of circle
Area of Rectangle: 10m * 6m = 60m^2
Circle Diamater: 6m
Circle Radius: 6m/2 = 3m
Circle Area: pi*(3m)^2
Circle Area: 28.27 m^2 Round to 28 m^2
Area of Shaded Region: 60m^2 - 28m^2 = 32m^2
