The two triangles may be congruent, but additional measurements are needed.
One of the cases of congruent triangles is when one side of the first triangle is the same as the same side of the second triangle and when There is an Angle between these ribs. We don't know the angle
perimeter of the sector is the sum of the lengths of all its boundaries.thus the perimeter of the sector is L+2r units. θ 360 × 2 π ( r ) + 2 r That would be the length of the arc in the first part and twice the radius in the second part.

Solve for r.
r=
Multiply by 2 to get diameter.
Answer:
The volume is 
Step-by-step explanation:
we know that
The volume of the sphere is equal to

we have
----> the radius is half the diameter

substitute the values

Answer:
B. -1
Step-by-step explanation:
STEP 1: Simplify 3x+2(x−9).

STEP 2: Add 8x and x.

STEP 3: Move all terms containing x to the left side of the equation.

STEP 3: Move all terms not containing x to the right side of the equation.

STEP 4: Divide each term by −4 and simplify.
