Answer:
41.24 cm²
Step-by-step explanation:
Here is the complete question: A 3 cm by 3 cm rectangle sits inside a circle with radius of 4 cm. What is the area of the shaded region?
Given: measurement of rectangle is
Radius of circle is 4 cm.
We can find the area of shaded region by subtracting area of rectangle from area of circle.
First, lets find the area of rectangle
Formula; Area of rectangle=
Area of rectangle=
∴ Area of rectangle= 9 cm²
Now, finding the area of circle.
Formula: Area of circle= (∵ r is radius)
Area of circle=
∴ Area of circle= 50.24 cm²
Next solving to find area of shaded region.
Area of shared region=
Area of shaded region=
∴ Area of shaded region= 41.24 cm²
Answer:
C) 12.5
The length of BC = 12.5cm
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that ΔABC</em>
<em>Given that AB = 15cm and ∠A = 40°</em>
<em>we will use trigonometric function</em>
<em> </em><em></em>
<em> </em><em></em>
<u><em>Step(ii):-</em></u>
we know that tan40° = 0.83909
BC = 15 × tan 40°
BC = 12.58649
BC = 12.5cm
<u><em>Final answer:-</em></u>
The length of BC = 12.5cm
