Answer:
176.7cm^2
Step-by-step explanation:
Area of circle = π ×r^2
π×15^2
and then divide by 4 because it's one quarter of a circle
Answer:
Therefore the area of the quadrilateral =35 cm²
Step-by-step explanation:
Given, the length of one of diagonal of quadrilateral is 10 cm and perpendicular drawn from the opposite vertices to this diagonal are the length of 2.8 cm and 4.2 cm.
A diagonal divided a quadrilateral into two triangle.
Therefore the area of the quadrilateral
= sum of the area of the triangles
cm² [ area of a triangle
]
=35 cm²
Answer:
-1
Step-by-step explanation:
We can use the formula to find slope
(y2-y1) / (x2-x1)
y1 is the first Y coordinate in the first pair
y2 is the second one in the first pair
X1 is the first X coordinate in the frst pair
x2 is the second one In the second pair.
so if we put it together it’d look liek this
(5- (-) 2) / (-4 - 3)
5+2 / -4 + -3
7/-7
or -1
Answer:
In a circle, interior angles that are not inscribed or central can be found using the formula < = larger arc + smaller arc / 2. So, in order to find <2, the formula would be <2 = 147 + 133 / 2, so 140.
