Answer:
916.1 cm^3
Step-by-step explanation:
1) find the radius of the cylinder:
radius = dimater / 2 = 7,3 / 2 = 3.65 cm
2) find the base area of the cylinder:
base area = radius^2 x 3.14 = 3.65^2 x 3.14 = 41.83265 cm^2
3) find the height of the cylinder:
height = 7.3 x 3 = 21.9 cm
4) find the volume
V = base area x height = 41.83265 x 21.9 = 916.135035 cm^3
5) round to nearest tenth:
916. 1 cm^3
I think it might be 7 don't know what answers you may have but its a guess
871 miles ........... 13 hours
469 miles ............x hours
x = 469×13/871 = 7 hours
Answer:
9 m
Step-by-step explanation:
Suppose AB is the ladder. AC is the height of the window above the ground and BC is the distance of the foot of ladder from the wall.
The triangle ABC is right angled at C.
∴ AB² = AC² + BC²
=> 15² = 12² + x²
=> 225 - 144= x²
=> 81 = x²
=> 9 = x
- Hence, distance of the foot of the ladder from the wall is 9 m.
