posledela

Answer:

4.17 centimeters

Step-by-step explanation:

The large bottle of nasal spray is 9.46 centimeters tall. Assuming that the large bottle of nasal spray has the shape of cylinder, then the height of the cylinder is 9.46 centimeters.

The small bottle is 5.29 centimeters tall. Assuming that the small bottle of nasal spray has the shape of a cylinder too, then the height of the cylinder is 9.46 centimeters.

We want to know how much shorter the smaller bottle is than the big bottle. This is calculated by

Height of big bottle - height of small bottle

= 9.46 centimeters. - 5.29 centimeters

= 4.17 centimeters

Mr. Williams is painting only the back of his barn. A gallon of paint covers 70 square feet. How many square feet will Mr. Willi
Alex17521 [72]

Answer:

Option A. 264 ft² ; 4 gallons

Step-by-step explanation:

Given question is incomplete; find the complete question in the attachment.

From the picture attached,

Area of the barn to be painted = Area of the (rectangular base + Triangular top) - Area of the window

Area of the rectangular base = 12 × 18

                                                = 216 ft²

Area of the triangular top = \frac{1}{2}(\text{Base}\times \text{Height})

                                          = \frac{1}{2}(12)(28-18)

                                          = 60 square feet

Area of the window = 3 ft × 4 ft

                                 = 12 ft²

Total area to be painted = 216 + 60 - 12

                                         = 264 ft²

∵ 70 square feet of the barn is covered by the amount of paint = 1 gallon

∴ 1 square feet will be covered by the amount = \frac{1}{70} gallons

∴ 264 square feet will be painted by = \frac{264}{70}

                                                             = 3.77 gallons

                                                             ≈ 4 gallons

Therefore, Option (A). 264 ft²; 4 gallons will be the answer.
