Answer:
Acute
Step-by-step explanation:
7² + 9² ? 11²
49 + 81 ? 121
130 is greater than 121, so it is an acute triangle
Answer is D because C^2 ×D^2 the * mean ×
Answer:
$672
Step-by-step explanation:
First find the area so:
5*4=20ft
2^2*3.14=12.56ft
20+12.56=32.56ft
Second find the price for the area:
32.56*12=$672
Hopefully it's correct!
Answer:
<u>274 square units</u>
Step-by-step explanation:
<u>Surface Area of the prism</u>
- SA = 2(base x height) + 2(length x height) + 2(base x length)
- SA = 2(bh + lh + bl)
<u>Here</u> :
- b = 4
- h = 5
- l = 13
<u>Solving</u>
- SA = 2(4 x 5 + 13 x 5 + 4 x 13)
- SA = 2(20 + 65 + 52)
- SA = 2(137)
- SA = <u>274 square units</u>
