Answer:
4xπ^3
Step-by-step explanation:
Okay, first we need to calculate the area of the rectangle.
Area of Rectangle- 16 x 6 = 96
Next, we need to calculate the area of the semicircles.
Formula: Radius x Radius x pi (3.14) = Area of circle
Since we know that the diameter is 6 we can figure out the radius.
The radius is half of the diameter. So our radius is 3.
3 x 3 x 3.14 = 28.26
Since it's a semi circle we now need to divide by 2.
28.26 divided by 2 = 14.13
Then, we add.
Area of rectangle
+
Area of 2 semi circles
96 + 14.13 + 14.13 = Total Area of The Figure
So our answer is 124.26
Simple interest = Cost Price + (Interest Percentage of Cost Price × number of years or months we are paying off)
a) SI = £20 000 + (5% of £20 000 × 4)
SI = £20 000 + (£1000 × 4)
SI = £20 000 + £4000 = £24 000
b) SI = £20 000 + (5% of £20 000 × 3)
SI = £20 000 + (£1000 × 3)
SI = £20 000 + £3000 = £23 000
£24 000 - £23 000 = £1000 that you saved!
Electronics- 40%
industrial design- 20%
civil engineering- 100%
not sure but best of luck :)

Combine like terms
8x + 71 = 7
Subtract the 71 to get x all alone
8x = -64
Divide by 8
X= -8
