Answer:
Try 6,400
Step-by-step explanation:
Find the volume of one congruent bookshelf then you'd be doing "4 x 10 x 8 x 10" (not another 8 bc they are talking about the length of the same side) you should get the answer 3,200 then multiply by 2 bc they're 2 bookshelves . You should get 6,400 I'm not 100% sure tho
15. If u take 8 and divide it by 12 then u get 3/4. Then multiply 21 by 3/4 (or .75) and it gives you 15.75. Since u can't win three quarters of a game, u round it down to 15
No it would be Pi *r *r because the r is to the power of 2
Answer:
286 mm²
Step-by-step explanation:
A trapezium is given with ,
- Parallel sides = 24mm , 28 mm
- Height = 11mm .
<u>The </u><u>area </u><u>is </u><u>given</u><u> by</u><u> </u><u>:</u><u>-</u><u> </u>
Area = 1/2 ( b₁ + b ₂) × h
Area = 1/2 ( 24 + 28)×11 mm²
Area = 1/2 × 52× 11mm²
Area = 286 mm²
<h3>
<u>Hence </u><u>the</u><u> </u><u>area </u><u>of</u><u> the</u><u> </u><u>trapezium</u><u> </u><u>is </u><u>2</u><u>8</u><u>6</u><u> </u><u>mm²</u><u>.</u></h3>
Answer:
(x+3)² + (y-2)² = 16
Step-by-step explanation:
the equation of a circle is
(x-a)² + (y-b)² = r²
with (a,b) being the center, and r the radius.
