Answer:
Area of the figure = 31.25π cm²
Perimeter of the figure = (12.5π + 10) cm
Step-by-step explanation:
Area of the given figure = Sum of area of the two semicircle + area of a quarter circle
Area of one quarter circle (CDE) = 
= 
= 6.25π
Area of one semicircle = 2 × Area of one quarter circle
= 2(6.25π)
= 12.5π
Area of the given figure = 2×12.5π + 6.25π
= 25π + 6.25π
= 31.25π cm²
Perimeter of the figure = Perimeter of two semicircles + perimeter of one quarter circle + measure of radius DE + measure of radius AB
Perimeter of one semicircle = πr
= 5π cm
Perimeter of one quarter circle = 2.5π
Perimeter of the complete figure = 10π + 2.5π + 5 + 5
= (12.5π + 10) cm
Answer: x = -1/2y + 2
Step-by-step explanation:
12x + 6y = 24 To solve for x first start by subtracting 6y from both sides
- 6y -6y
12x = 24 - 6y Now divide each side by 12
x= 2 - 1/2y
5 x =5x because 2 turns to 3 so 3 turns to 5
Set up a proportion. Let h = the statue height. h/statue shadow = boy height/boy shadow.
h/25 = 4.5/3.6
Cross multiply and solve for h.
