Answer:
Step-by-step explanation:
<u>Given vertices of triangle:</u>
- A(1, 2), B(3, 4), C(5, 0)
<u>The centroid is found as the average of x- and y- coordinates of three vertices:</u>
- C = ((x₁ + x₂ + x₃)/3, (y₁ + y₂ + y₃)/3)
<u>Substitute the coordinates into formula:</u>
- C = ((1 + 3 + 5)/3, (2 + 4 + 0)/3) = (3, 2)
Correct choice is B
Answer:cube root 381.7
Then half it too find the radius.
Step-by-step explanation:
Answer:
8x-15y=84
Step-by-step explanation:
Multiply 12 to both sides to get rid of the fractions.
The formula of cylinder: 兀r^2×altitude
Take 兀 as 3.14
In this case,the equation will be:
兀1.5^2×3.5
=2.25兀×3.5
=7.875(3.14)
=24.7275
≈24.74
Thus the answer is B.24.74 m3.
hope it helps!
