<span>The area of wall that will be painted in one roll would be equal to the curved surface area of the roller. Therefore, the curved surface area of roller= 2*pie*radius*height
Given: pie=3
So, Curved Surface Area of the roller=2*3*5*13 sq. in.
= 390 sq.in
Therefore, Area of the wall painted in one roll is equal to 390 sq.in.
While Area of the wall painted in 3 rolls will be (390*3) or 1170 sq.in</span>
Divide 4 7/8 by 3/8:
or 39/8 by 3/8. We can drop the denominators 8 and 8 and find 39/3 = 13.
This guy needs 7 more pieces to end up with 20 pieces.
Answer:
368
Step-by-step explanation:
just multiply 46 x 8 = 368
5 ≥ 2, so the second rule of <em>C(x)</em> applies :
<em>C</em> (5) = 25 + 3•(5 - 2) = 25 + 3•3 = 25 + 9 = 34
