A=spr=(180-90)÷2=45
answer: a=45
Answer:
1.) can not be found
2.)V=11403.98
3.)
Step-by-step explanation:
volume = π r×r × H
r = Radius
H = height
π = 3.14
the first one does not have a radius so therefore we can NOT find the volume
the second one is π×(11×11) ×30 =11403.98
the 3rd one is π× (10×10) ×5 =1570.79
hope this helped
multiply the bill by 15% and then add them together:
58.65 * 0.15 = 8.797 = 8.80
58.65 + 8.80 = $67.45 total
Answer:
The length of BE is 5.5 units.(A correct option)
Step-by-step explanation:
Given diameter AC intersects chord BD at point E such that AE = 2.5 units and DE = 3.4 units. Point O is the center of the circle, and the radius of the circle is 5 units. we have to find the approximate length of BE.
CE=CO+OE=5+(OA-AE)=5+2.5=7.5 units.
Now, by Intersecting Chord Theorem which states that when two chords intersect each other inside a circle then the products of their segments are equal.

Hence, the length of BE is 5.5 units.
