Answer:
![143.8\:\mathrm{ft^2}](https://tex.z-dn.net/?f=143.8%5C%3A%5Cmathrm%7Bft%5E2%7D)
Step-by-step explanation:
The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:
Area of semi-circle (half the area of a circle): ![\frac{1}{2}\cdot 4.5^2\cdot \pi](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ccdot%204.5%5E2%5Ccdot%20%5Cpi)
Area of trapezoid (average of bases multiplied by height): ![16\cdot 7](https://tex.z-dn.net/?f=16%5Ccdot%207)
Thus, the total area of the figure is:
![\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ccdot%204.5%5E2%5Ccdot%20%5Cpi%2B16%5Ccdot%207%3D143.808625618%5Capprox%20%5Cboxed%7B143.8%5C%3A%5Cmathrm%7Bft%5E2%7D%7D)
The answer is 296,000,000.
Answer:
ok ill be your friend ok dont worry
Hi there
Let's order the transactions
on May 1. 150
less On May 20 100 books were sold
Less June 3, 31 books were purchased by the students
Add on June 15 25 books arrived
Add On June 17, a shipment of 150 books arrived
So
the number on hand on June 17
150−100−31+25+150
=194....answer
Hope it helps
