Answer:
1) 18
2) 6
3) 12
4) 12
5) 7
6) 9
Step-by-step explanation:
1) 2*x = 6^2, 2x=36, x = 18
2) 2*(x+2) = 4^2, 2x+4 = 16, x = 6
3) 10^2 = 5 * (x+8), 100 = 5*(x+8), x = 12
4) The altitude is 4sqrt3 using pythagorean, (4sqrt3)^2 = 4*x, 48 = 4*x, x=12
5) Altitude is sqrt63 using pythagorean, (sqrt63)^2 = 9x, x = 7
6) Altitude is sqrt72, sqrt(72+9) = 9
Answer:
Step-by-step explanation: I only know for number 12 sorry but here railroad tracks, the edges of sidewalks, marking on the streets, zebra crossing on the roads, the surface of pineapple and strawberry fruit, staircase and railings, etc.
Given that the ball has a thickness of 1 cm and the radius at the outside is 5 cm, thus the radius from inside is 5 - 1 = 4cm.
The <span>approximate volume of rubber used to make the ball is given by the volume of the ball at the outside surface minus the volume of the ball at the inside surface.
