Round 956 to the nearest 5

Answers

Answer:

957

Step-by-step explanation:

By using basic property of rounding we got that nearest 5 of 956 is 955.

What is rounding of numbers ?

Rounding means making a number more simpler by keeping its value close to original value .

For round to the nearest 5 we round up or down the number to nearest multiple of 5

for example if number is 16 we will round down it to 15 and if number is 18 we will round up to 20 and if number is 12 we will round down to 10.

Here given number is 956

Two nearby multiple of 5 are 955 and 960 but we can see that 955 is more closer than 960 so we will round down 956 to 955.

By using basic property of rounding we got that nearest 5 of 956 is 955.

Find the Perimeter of the figure below, composed of a parallelogram and one
semicircle. Rounded to the nearest tenths place

Answers

Answer:

38.6 units.

Step-by-step explanation:

The given figure is composed of a parallelogram and one  semicircle.

We need to find the perimeter of the parallelogram.

Perimeter = sum of all sides

ATQ,

P = 9+8+9+(2πr/2)

i.e.

[tex]P=26+\pi r\\\\=26+3.14\times 4\\\\=38.56\ \text{unit}[/tex]

or

= 38.6 units

So, the perimeter of the figure is equal to 38.6 units.
