1) 2 x 7 x 2 = 28
28 + (3 x 7 x 5) = 54 cm cubed
Answer:
13.9 or 14
Step-by-step explanation:
a^2 + b^2 = c^2
5^2 + 13^2 = c^2
25 + 169 = 197
square root 197 to get c
c = 13.9 (14 rounded up)
Helpful thing to note is that the hyptoenuse will always be longer than your "long side" of the triangle
The answer is 7.
6/4 = 3/2
(3/2) / (3/14) = (3*14)/(2*3) = 42/6 = 7
