Octagon, stop sign.
Eight isoscles triangles. It looks like we're told the side is 9.9 and the height to the side (also called the apothem) is 12.
So each isosceles triangle has area (1/2)(9.9)(12) and we have eight of them,
area = 8(1/2)(9.9)(12) = 475.2
Answer: 475.2
Usually we wouldn't be told 9.9 -- this is the baby version. We know each of those isoscles triangles has unique angle 360/8=45 degrees, so the apothem and half the side of the octagon are a right triangle with acute angle 22.5 degrees.
The area of the right triangle with long leg 12, short leg x,
tan 22.5 = x/12 or
x = 12 tan 22.5
Twice that is what we're told is 9.9; let's check:
2x = 24 tan 22.5 = 9.941125496954282
The area of the little right triangle is
(1/2) 12 × 12 tan 22.5
and there are 16 of these
16 (1/2) 12 × 12 tan 22.5 ≈ 477.174
Answer:86 seconds
Step-by-step explanation: First, 100 yards would be 52 seconds, but she wants 150 half of 52 is 26. 52+26=86
Your question is difficult to understand, that is why I am going to edit your question as follow:
<u>Edited Question:</u>
Cone A and B both have a volume of 48π Cubic units but have different dimensions. Cone A has a radius=6 units and a height=4 units.
Find the one possible radius and height for cone B be to have the same volume as cone A.
Answer:
Radius of cone B= 6units
Height of cone B=units
Step-by-step explanation:
As we know the formula for the volume of a cone is
If volume of A and Volume B is given as same, thus
comparing equations above, we get
Thus, Radius of cone A=6units
and
Height of cone B= 4units
