Lets split this into two parts; a semi circle and triangle. We can solve fro the area of both individually first.
Area of the Semi Circle:
Formula: A = (πr²)/2
The radius is the diameter divided by two (16 / 2 = 8)
A = (π*8²)/2
A = (π64)/2
A = 200.96/2
A = 100.48 meters
The area of the semi circle is 100.48 meters
Area of the Triangle:
Formula: A = bh/2
A = 16*12/2
A = 192/2
A = 96 meters
The area of the triangle is 96 meters.
To find the total area of the shape, we can add.
100.48 + 96 = 196.48 meters.
Best of Luck!
Answer:
<u>254.34 in²</u>
Step-by-step explanation:
<u>Area of a circle</u>
- <u>r = radius of the circle</u>
<u>Solving</u>
- A = 3.14 x (9)²
- A = 3.14 x 81
- A = <u>254.34 in²</u>
Answer:
25
Step-by-step explanation:
a1 = 9
a2 = a1 + 4
a2 = 9 + 4
a2 = 13
a3 = a2 + 4
a3 = 13 + 4
a3 = 17
a4 = 21
a5 = 21 + 4
a5 = 25
This can more easily be done by using this formula
L = a1 + (n - 1) * d
a1 = 9
n = 5
d = 4
L = 9 + (5 -1)*4
L = 9 + 4*4
L = 9 + 16
L = 25
