Step-by-step explanation:
<u>We can estimate the dividend and divisor as follows:</u>
- 635943 ÷ 77 =
- 636000 ÷ 80 =
- 7950 ≈ 8000
Estimate is 8000
Answer:
A = 21 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (b₁ + b₂ )
where h is the height between bases and b₁, b₂ are the parallel bases
Here h = 3, b₁ = 9, b₂ = 5 , then
A = × 3 × (9 + 5) = 1.5 × 14 = 21 cm²
<u><em>Answer:</em></u>
Area of the circle = π square units ≈ 3.14 square units
<u><em>Explanation:</em></u>
To get the area of the circle, we first need to get the length of its radius
<u>1- getting the radius of the circle:</u>
We are given that the circumference of the circle is 6.28 units
Circumference = 2πr
where r is the radius and π has an approximate value of 3.14
6.28 = 2 * 3.14 * r
r = 1 units
<u>2- getting the area of the circle:</u>
Area of circle = πr²
Area of circle = π * (1)² = π square units ≈ 3.14 square units
Hope this helps :)
