A lunette is a semi-circle, which means that it is one half of a circle. To find its area, we can find the area of the whole circle and divide it by two.
Area of a circle: A = pi x r^2
r = 40 / 2 = 20
A = pi x 20^2
A = 400pi / 2 = 200pi
200pi = 628.32
The area of the lunette is approximately 628 in^2.
Hope this helps!! :)
Answer:
RSTU is a parallelogram, quadrilateral, rectangle, rhombus, and square. NOT trapezoid.
Step-by-step explanation:
The shape has four sides, so it's a quadrilateral.
It has four equal sides so its a rhombus.
It has four right angles so its a rectangle.
It has four equal sides AND right angles so its a square.
And if all the sides are parallel (well, two pairs of parallel sides) its a parallelogram.
Answer:
No, since when you multiply a number by 0, that means you are not adding that number to the sum which is 0. Since there is no addition going on, the answer is 0, so when you multiply any number by 0, the answer is 0.
