Use compatible numbers to find two estimates 1322 divided by 18

1 answer:

5 0

Compatible numbers is used to find estimate to a sum. The numbers are chosen because its 'simplicity' when they are multiplied, divided, added or subtracted.

Estimate one:

We can decrease the value 1322 to 1320 and 18 to 15
Then do the sum = 1320÷15 = 88
This estimate is not far from the actual answer 1322÷18 = 73.44..

Estimate two:

We can increase 1322 to 1330 and 18 to 20
Then do the sum 1330÷20=66.50
This estimate is also not far from the actual answer 73.44...

Step-by-step explanation:

Given

Shape: dome

$r = 12$

Required

The surface area

This is calculated as:

$Area = 3\pi r^2$

So, we have:

The perimeter of a rectangular meadow is 1004 m. What

nadezda [96]

Answer:

hope it works for u

Step-by-step explanation:

Given the length of the rectangle = l

the breadth of the rectangle = b

perimeter of the rectangle = sum of length of all sides of the rectangle

= l+ b+ l+ b

=2 l+2 b

=2( l+ b)

∴ perimeter of the rectangle =2( l+ b)

as given perimeter = 1004 m

hence ,

2(l+ b)= 1004

(l+ b)=1004/2 = 502 m
