Answer:
Step-by-step explanation:
area of base = π4² = 16π in²
lateral area = 2πrh = 2π·4·6 = 48π in²
surface area = 2×16π + 48π = 80π in² ≅ 251.3 in²
Answer:
$8
Step-by-step explanation:
20% is 1/5, so you can basically divide $40 by 5, which is $8.
Answer:
49x + 114
Step-by-step explanation:
[ [ fireplace ] x = area of 5
] x + 6
5x
patio = area of 5
+ 49x + 114
5x + 19
(5x + 19) ( x + 6) = 5
+ 19x + 30x + 114
(5
+ 49x + 114) - (5
) = 49x + 114
(area of patio and fireplace) - (area of fireplace) = (area of patio only)
Answer:
yes it is.
Step-by-step explanation:
because there isn't any repeated x.
so it is a function.
Answer:
no
Step-by-step explanation:
Similar triangles have angles with the same measures.
angles in the first triangle are 50°, 60°, 70°.
angles in the second triangle are 50°, 50°, 80°.
The angles do not have the same values, so the triangles cannot be similar.
_____
<em>Comment on the question</em>
When 2 of the three angles are different, the third angle cannot make the triangles similar. We don't even need to compute the third angle to answer this question.
