Answer: 16 miles is the total
Step-by-step explanation:
12 = 3x/4. Or 12/x : 3/4
12/3 = 4. 4×4=16
The area of the shaded region is
.
Solution:
Given radius = 4 cm
Diameter = 2 × 4 = 8 cm
Let us first find the area of the semi-circle.
Area of the semi-circle = 


Area of the semi-circle =
cm²
Angle in a semi-circle is always 90º.
∠C = 90°
So, ABC is a right angled triangle.
Using Pythagoras theorem, we can find base of the triangle.




cm
Base of the triangle ABC =
cm
Height of the triangle = 4 cm
Area of the triangle ABC = 

Area of the triangle ABC =
cm²
Area of the shaded region
= Area of the semi-circle – Area of the triangle ABC
= 
= 
Hence the area of the shaded region is
.
Answer:
30 feets
Step-by-step explanation:
subtrqct 55-25 = 30
I’m not sure that this is 100% right but i would do tan37° x 12 to get: -10.1
