Answer:
Step-by-step explanation:
Semicircle:
Shaded area of semicircle = area of outer semicircle - area of inner semicircle
Outer semicircle:
d = 40 m r = 40/2 = 20m
Area of outer semicircle = πr²
= 3.14*20*20
= 1256 m²
Inner semicircle:
d = 30 m r = 30/2 = 15 m
Area of outer semicircle = πr²
= 3.14*15*15
= 706.5 m²
Shaded area of semicircle = 1256 - 706.5 = 549.5 m²
Shaded area of semicircle in both sides = 2 * 549.5 = 1099 m²
<u>Rectangle on both sides:</u>
Length = 50 m
width = 30 m
Area of shaded rectangles on both sides = 2* (length *width)
= 2* 50 * 30
= 3000 m²
Shaded area = 1099 + 3000 = 4099 m²
Answer: 2x
Step-by-step explanation:
6x2y2 - 8xy2 + 10xy3
- 3 ,2 , x, x, y, y - 2xyy
= 4, 2 , x, y , y- 2xyy
10x = 5, 2, x ,y ,y, y - 2xyy
The diagonals would be perpendicular (intersect at a 90* angle)
Whenever we multiply values where the bases are the same, you add the exponents.
2+4=6, so the answer is
5^6
