We will use the circumference formula to find the radius and then multiply it by 2 to find the diameter.
C = 2πr
31.4 = (2)(3.14)(r)
31.4 = 6.28r
5 = r
So our radius is 5 in.
We can multiply it by 2 to get the diameter.
5*2 = 10
So the diameter is 10 inches
Answer:
906 inches³
Step-by-step explanation:
The volume of a triangular pyramid = 1/3 (area of base) × h
area of the base = 1/2 × 19 × 13 = 123.5 inches²
v = 1/3 × 123.5 × 22 = 905.666... ≈ 906 inches³
The volume of the triangular pyramid is 906 inches³
Hope this helps!
Answer:
FALSE.
An isosceles triangle may be right or acute or obtuse,the angles measure (90°,45°,45°) or (60°,60°,60°) or (120°,30°,30°) respectively.
The correct answer is -1.
In order to solve this, we need to split into the positive and negative version of the answers. Let's start with the positive version.
2 - x < 4
-x < 2
x > -2 ----> NOTE: When we divide by -1, we have to change the direction of the sign.
Now we'll do the negative version.
2 - x > -4
-x > -6
x < 6
So we know the number must be greater than -2, but less than 6. The only number on this list that fits that is -1.
