Answer:
Volume of composite is 483
Step-by-step explanation:
We need to add the volume of a rectangular prism (7 mm x 12 mm x 3 mm) to a semi-cylinder (of radius 3.5 mm and height 12 mm):
Volume of the prism = 7 x 12 x 3
= 252
Volume of the semi-cylinder = 
Therefore the sum of both volumes gives:
(252 + 230.907)
= 482.907
WHich can be rounded to the nearest whole number as: 483
Answer:
310
Step-by-step explanation:
Use the Order of Operations method. (P.E.M.D.A.S.)
Our expression: 3+2⋅4+62⋅5−1
<u>Multiply 62 and 5, and 2 and 4:</u>
3+8+310-1
<u>Add and Subtract from left to right:</u>
11+310-1
311-1
310
The ratio is 6:18 and you are trying to find out what are blue. You divide 240 by 6 and get 40. You then multiply 40 x 18 and get 720.
