Answer:
measure of angle 3= 41
Step-by-step explanation:
complementary= 90 degrees
angle 3+ angle 4= 90 degrees
90-49=41
It’s A
You take the smallest number for min
And largest number for max
then do process of elimination
It can’t be a negative either
0
Step-by-step explanation:
for this question is not even possible
Answer:
S = 128πx² + 64πx + 8π
Step-by-step explanation:
Suraface area of a cylinder is given by:
S = 2πrh + 2πr²
We know that the height is 3 times as big as the radius, hence:
h = 3r
so we can plug in the new h value and rewrite the S equation as:
S = 2πrh + 2πr²
S = 2πr(3r) + 2πr²
S = 6πr² + 2πr²
S = 8πr²
We're given in the question that the radius is (4x + 1) inches, so plug that into r.
Given: r = 4x + 1
Therefore,
S = 8πr²
S = 8π(4x + 1)²
S = 8π(16x²+8x+1)
S = 128πx² + 64πx + 8π
100/6 = 16.66 rounds to 16.7
