= 2x^3 +8x^2 +16x - x^2 -4x -8
= 2x^3 +7x^2 +12x -8
Yes a triangle is formed with given measurements
By using Heron’s formula
S=a+b+c/2
S=240+132+330/2=351
Area = root of s(s-a)(s-b)(s-c)
By substituting the values
We get that 13385.874....
Answer: 2000.18 unit^3
Step-by-step explanation:
radius = 14 / 2 = 7
V of cylinder = π x r^2 x h
= 3.14 x 7^2 x 13
= 3.14 x 49 x 13
= 2000.18 unit^3
If cos(70) = 0.342
the cosine of the alternative angle of 70° will also give the same value
angle measure = 360 - 70 = 240°
cos (240) will also be 0.342
She can fill 5 bird feeders because if you turn 2 7/8 into a decimal it is 2.875, and 2.875 x 5 = 14.4. To be sure, you can turn 14 4/5 into a decimal which is 14.8.
