erastova [34]
Volume of a cylinder = Height x base are
H = 6.2 m
Bae are = π.R² ; Diameter =4.4 m, then Radius = 2.2 m
Base area = π(2.2)²
And Volume=:
V= (6.2).(π,2.2²) = (6.2).(π)(.4.84) = 30.008.π ≈ 94.2 m³

Zach painted 92 square feet in the same amount of time that Blaise painted
Alika [10]

Answer:

The answer to your question is 252 in²

Step-by-step explanation:

Data

Zach = 92 ft²

Blaise = 13500 in²

Who painted more and how many more square inches? = ?

Process

1.- Convert the square feet to square inches

            1 ft² ----------------- 144 in²

          92 ft² ----------------   x

            x = (92 x 144)/1

            x = 13248 in²

2.- Subtract the lower value to the higher value

Area = 13500 in² - 13248 in²

Area = 252 in²

3.- Conclusion

Blaise painted 252 in² more than Zach.
