CE = CD + DE = 2DE + DE = 3DE = 8.7
DE = 8.7/3 = 2.9
CD = 2DE = 5.8
For the inscribed circle, where center is point D. The radius is length DE.
This is because the circle will touch the 3 points where the bisectors intersect with sides of triangle.
radius = 2.9
For circumscribed circle, the center will also be point D. The radius is CD.
The circle will touch 3 points of triangle, A,B,C.
radius = 5.8
Answer:
1017.9
Step-by-step explanation:
Find the area of the circle on top first using 3.14*r^2
3.14*9^2 = 254.5
Multiply this number by the height, 4
254.34*4 = 1017.9
Answer:
sin60 = p/h
√3/2 = 2/x
x = 4/√3 × √3/√3 = 4√3/3unit.
Answer:
The fact that the two lines have the same slope is proof that they are parallel.
Answer:
Step-by-step explanation:
When plotting numbers on a number line, we need to know about negative and positive numbers. So basically, if we start from zero and go infinitely to the right, we are going in the positive direction. If we are going to the left, it's negative. As we go to the left, the larger the base number is (number without the sign negative) the less value it is. Since you are plotting 9,2, and -4, we put 9 one before 10. 2 is 2 little slashes from 0. Lastly, -4 is 4 to the left from 0. Hope this helps!
