Answer Perimeter = 33in
Step-by-step explanation:
AC = 20
BD = 20
AB = 13
O is the midpoint
OD = OC = 20/2 = 10
AB = DC = 13 in
P = DC + OD + OC = 13+10+10 = 33in
Answer:
b
Step-by-step explanation:
Check the picture below.
the triangle is an isosceles, so it has twin legs, and a base bottom.
the twin sides stem from the "vertex", and we know the vertex is 120°, and since the triangle is inscribed in a circle, because the circle is "circumscribing" it, then the base side of the triangle will be the diameter of it.
if we run a perpendicular line to the base from the vertex, we'll split the vertex in two 60° angles, as you see there, giving us a 30-60-90 triangle on each side.
so, anyhow, the rest is just a matter of using the 30-60-90 rule.
that's the diameter, and as you know, the radius is just the length of the base, or half the diameter.

Answer:
V = 24 m³
Step-by-step explanation:
The given question says that, 'Calculate the volume in cubic meters of a pool that is 8 m long, 2 m wide and 1.5 m deep'.
A pool is in the shape of a cubiod. The volume of the cuboid is given by :
V = lbh
Where
l is length, b is width and h is height
Put all the values,
V = 8 × 2 × 1.5
= 24 m³
So, the volume of the pool is equal to 24 m³.
