Can someone pls answer these questions thks ok1 . a cylinder whose diameter is 6 cm and whose height is 4 cm then find its volume 11 . a cube whose edge is 3.5 inches Pls use V=Bh for both thanks anyone who answers
Answers
Answer 1
Answer:
OK. I think we can do that.
' V= b h ' means " Volume = (area of the base) x (height) "
That can work for both a cylinder and a cube. (But the cylinder has to be standing up on one end.)
-- Cylinder:
The base that it's standing on is a circular end. The area of a circle is A = π (radius)² . Radius = 1/2 of the diameter = 1/2 of 6 cm = 3 cm . Area of the circular base = π (3 cm)² = 9 π cm² Height of the cylinder = 4 cm V = b h = (9 π cm²) (4 cm) = 36 π cm³ = 113.1 cm³ (rounded)
-- Cube:
Every edge of the cube is the same length ... 3.5 inches Every face of the cube is a square. Area of a square = (side length)² Area of the base that the cube is sitting on = (3.5 inches)² Volume of the cube = b h = (3.5 inches)² (3.5 inches)
the answer is 93. its very simple to round well mosly for me cause im smart

A football team gained 35 yards on a first down, lost 15 yards on the second down and gained 12 yards on the third down. How many yards do they need to gain on the fourth down to have a ten yard gain from their starting position?
Answers
13 yards
35-15=20 20+12=32 32-35=3 3+10=13
300 is greater than 30 explain using rounding
Answers
yes 300 is greater and 30 is less then with rounding
30 x 10=300 therfore making 300 ten times larger.
What is 2 and 928 ten-thousandths as a decimal?

With a dilation, each dimension increases by the factor. Thus, if we let the dimensions be x and y, the new dimensions are 2x and 2y.
(a): The original perimeter is 2(x+y), but the new one is 2(2x+2y). This is twice the original perimeter, so it is 18*2=36.
(b): The original area is xy, and the new one is (2x)(2y), or 4xy. This is four times the original area, or 20*4=80.
(c): As it's given that the side lengths are integers, the intended solution is most likely to divide by 2 in the perimeter to see that the sum of the side-lengths is 9 and their product is 20. Guessing/checking values for each side, we see that 4 and 5 work for the smaller rectangle. Multiplying by two, the larger one has lengths 8 and 10.
Alternatively, we set them to x and y and use the equations: x+y=9 xy=20
Dividing by y, we see that x=20/y. Substituting, we have that y+20/y=9. Subtracting 9 and multiplying by y, we have:
y^2-9y=20
Factoring, we have (y-5)(y-4)=0. The solutions to this equation are 4 and 5, which result in x=5, y=4 or x=4, y=5 respectively. Thus, we see that 4 and 5 are the side-lengths. Note that this solution did not require the assumption that the side-lengths are integers!
16.437 rounded to the neatest tenth is 16.4 true or false
Answers
Answer=True
When rounding 16.437 to the nearest tenth, we need to look to the hundreds place.
16.437
The number 3 is in the hundreds place
The rules of rounding are:
If the number is 5 or greater, then you round up.
If the number is 4 or less, Then you round down.
Since 3 is less than 4, we would round down. So...
16.437 becomes 16.4
It is true because after the decimal the digit is in the tenths catagory then hundreths and thousandths etc. That is why it is tenths. :)
