Step-by-step explanation:
<u>Subtractive Areas
</u>
When we want to find areas of surfaces that are inside of greater surfaces, we must subtract the greater minus the rest of it. We want to find the shaded area which is part of the circular sector, along with a right triangle shown in the figure. The area of a circle is
The area of a circular sector of center angle \theta is
The area of a right triangle with base b and height h is
We have the value of is
The radius is half the diameter, thus
The area of the circular sector is computed now:
We also have the length of the base as double of the given value (because of symmetry)
The height is
The area of the triangular surface is
Finally, the shaded area that Geneva will lose from the table is
Answer:
x = 3
Solved by cross multiplying the fractions.
Answer:
No. Angle 1 is an obtuse angle while angle 2 is an acute angle. obtuse angles are more than 90 degrees, which is more than an acute angle's less than 90 degrees.
Step-by-step explanation:
Step-by-step explanation:
When t = 2,
h(2) = 8 + 40.8(2) - 16(2)² = 8 + 81.6 - 64 = 25.6
Therefore the height after 2 sec is 25.6.
