It's a half circle plus a triangle.
The diameter of the circle is 23.1 ft so the radius is 11.55
Area of a circle is πr²
Area of a triangle is (1/2)bh
Area shape = (1/2)πr² (1/2)bh
A = (1/2)π(11.55)² + (1/2)(23.1)(29.4)
A = 549.1181
Answer:$17,260 is how much more he will have to earn to pay for his degree!
Step-by-step explanation:First you have to multiply 7,215 with 4 and you get 28,860.Next you multiply 1,350 by 4 and you get 5,400.Then you add 5,400+4,200+2,000 and you get 11,600.Last but not least,you subtract 11,600 with 28,860 and you get $17,260!
There it is, I don't know what you mean by "describe the solution"
Ok so a rectangular prism is the same as a rectangular cuboid.
The surface area is all the areas of the faces added together ->
There are three different faces that occur twice
length -> l
width -> w
height ->h
2( l * w ) + 2( l * h ) + ( w * h )
2 ( 10 * 4.5 ) + 2 ( 10 * 8.75 ) + 2 ( 4.5 * 8.75 ) = 343.75 cm2
Therefore it's A
Hope this helps :P
