Step-by-step explanation:
Volume of Barrel : [pi x h(r² + 2R²)] / 3
Barrel A : 2pi(r² + 2R²)]/ 3
Barrel B : 5pi(r² + 2R²)]/ 3
Barrel A + Barrel B = 532
5pi(r² + 2R²)/3 + 2pi(r² + 2R²)/3 = 532
5pi(r² + 2R²) + 2pi(r² + 2R²) = 1596
7pi(r² + 2R²) = 1596
pi(r² + 2R²) = 228
Barrel A = 2 x 228/3 = 76 ft³ SMALLER
Barrel B = 5 x 228/3 = 380 ft³
hope it's helpful, I'm not sure if (r) and (R) are the same if the two barrels has a similar shape. but if they're the same, then the answer is correct
Answer:
The correct answer is the Number line with points marked for seven, eight, nine, ten, eleven, twelve. The eight-point is marked with an open circle pointing right.
2x^2+7x-4
you need distribute all the numbers in parenthesis.
Answer:
6) x = 17 ft
7) 42 in
Step-by-step explanation:
6) length of the tangents are equal.
2x - 7 = 27
2x = 34
x = 17
7) if you draw a line from T passing through the centre of the circle, it will divide the triangle into two congruent triangles
Perimeter = 2(5+7+9) = 42 in
