This is just cylinder surface area, right? Equation for that would be 2πrh+2πr^2. If we input the data given from the image, it’d be (2 x π x 3.5 x 4)+(2 x π x 3.5 x 3.5). (4 is the height, and I found the radius by dividing the diameter, 7, in half, which is 3.5.) if u plug that into a calculator, u get 164.93.
The multiples of 3 are 3, 6, and 9. There are 10 spots.
10/10 - 3/10 = 7/10
The answer is 7/10, 0.7, or 70%.
Z=11 is the answer for this problem
we are given
a number is 429
where 4 is underlined
For finding value of digits , we always start from right side
Firstly , it comes unit digit
multiply by 1
Secondly , it comes tenth digit
multiply by 10
Thirdly , it comes hundredth digit
multiply by 100
we can see that 4 is third digit from right
so, it will at hundredth place
To find it's value, we multiply by 100
so, we get
