Answer:
38.13m²
Step-by-step explanation:
We find the area of ;
Rectangule and semicircle
Area of rectangle :
Length * width
Length = 8m ; width = 3m
Area = 8 * 3 = 24m²
Area of semicircle = 1/2 πr²
Radius, r = 3m
A = 1/2 * 3.14 * 3²
A = 1/2 * 3.14 * 9
A = 14.13 m²
Area of patio :
(24 + 14.13)m²
= 38.13m²
Answer:
w = 7 7/8
Step-by-step explanation:
w + 1/8 = 8
First, subtract 1/8 from both sides of the equation
w + 1/8 = 8
- 1/8 - 1/8
w = 7 7/8
A = 1/2 bh
multiply each side by 2
2A = bh
divide each side by b
2A/b =h
The height of a triangle is equal to twice the area A divided by the base ,b.
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
Prove it by explain how the shapes are interacted or not
