Step-by-step explanation:
Given:
Volume of the cylindrical container before dilation,
Scale factor of the dilation,
Therefore, the volume of the dilated cylinder is given as:
Plug in 1 gal for and
for SF. Solve for
. This gives,
Therefore, the volume of the dilated cylinder is gallons.
Answer:
294.5 m²
Step-by-step explanation:
shaded region = area of major sector + area of triangle
central angle of major sector = 360° - 130° = 230°
area of sector = area of circle × fraction of circle
A = π × 11.1² ×
= ≈ 247.3 m²
area of triangle = 0.5 × 11.1 × 11.1 × sin130° ≈ 47.2 m²
shaded area = 247.3 + 47.2 ≈ 294.5 m²
