Given:
A bricklayer is able to set 2.5 bricks in one minute.
Required:
To find the number of bricks can he set in 8 hours.
Explanation:
8 hours =480 minutes.
2.5 bricks in one minute.
So for 480 minutes,
Final Answer:
1,200 bricks can he set in 8 hours.
6 with 2 refills seems like a better buy to me
Answer:
t=4.45
Step-by-step explanation:
Well, I'm assuming you haven't had your question answered yet in these 58 minutes. I'm not 100% sure but I would think that you would do the reverse of the equation to find the area of a circle to find the radius of the pizza cutter. So you would find the radius using the equation A=
r
to figure out the RADIUS. THEN, you would plug in the radius into the equation C=
to figure out the circumference. Next, you would multiply the circumference by 4. This would give you the diameter of the pizza. Finally, you would plug in the diameter of the pizza into this equation: A=
to find the area of the pizza. I am pretty sure this would work and there's probably an easier way that I don't know about. Assuming you get this in time, good luck! :)
The area of the square is 9 in^2
The side of a square is the square root of the area.
Side of square = √9 = 3 inches.
The side of the square is the diameter of the inscribed circle.
Circumference of a circle is PI x diameter.
Circumference of inscribed circle = 3.14 x 3 = 9.42 inches
The diameter for the circumscribed circle would be the diagonal of the square which is 3√2 = ( Side length x √2) ≈ 4.2426
The circumference = 3.14 x 3√2 = 13.321
Find the ratio between the two circles:
Circumscribed / inscribed =
13.321 / 9.42 = 1.41
