Need help on numbers 1 and 2 ill mark brainliest if they are right
geniusboy [140]

Question author, it's spelled pi not pie, and we use just use the Greek letter π.  Students, demand better from your teachers.

1. Rectangular prism, aka a box. Volume is length times width times height.

V = 5×7×9 = 315 cubic feet

That's cubic feet of course, the product of three lengths.  We didn't even need to do the problem, just look for the common answer and pick the one with the right units.  I just saw that same pattern in a volume problem yesterday.

Answer: 315 cubic feet, first choice

2. Cylinder, volume is base area times height, πr²h.   We have a radius of r=14/2=7 yd and h=8 yd.  We're using π=3.14.

V = πr²h = 3.14(7²)(8) = 1230.88 cubic yds

Answer: 1230.9 cubic yards, last choice

Which is equal to 7(3.5x10^4)written in scientific nation
k0ka [10]
The answer is 2.45 x 10^5. 

7 x 3.5 = 24.5

Move the decimal place over to the left until you have a number between 1 and 9 before the decimal point.

Add the number of times you moved the decimal point to the exponent (The 4 in the original equation).

2.45 x 10^5.

I hope this helps!

Number 3?? I can’t figure it out
monitta

divide the total cost by the number of hinges:

Mark's hardware: $28 / 8 = $3.50 per hinge

Steve's Supply: $39 /  11 = $3.45 per hinge.


$3.45 is less than $3.50, so the answer would be C.
