Hey there
I 've already answered this question twice
by mistake.Kindly check.
Answer:
Step-by-step explanation:
1) we have to find the area of the cut out portion
Since both circles in one side makes up the side 28cm
The diameter of each circle is 14cm
radius = diameter / 2
r = 7cm
Area of a circle = πr²
A = 22/7 × 7²
= 22/7 × 7 × 7
= 22 × 7 = 154cm²
So the four circles will make
= 154 + 154 + 154 + 154
= 616 cm²
The Area of the square will be
= L × L
= 28 × 28
= 784 cm²
Therefore the area of the remaining portion will be
Area of the square - total area of the circles
= 784 cm² - 616 cm²
= 168 cm²
The area of the remaining part is 168 cm²
For Question 1:
angle CAB, angle ABC, angle BCA
Question 2: angle BCD

Answer:
3.2%
Step-by-step explanation:
-Let r be the simple interest rate per annum.
-Given the total amount after 1 year is 1857.60, the initial amount is 1800
#We use the simple interest formula to find the rate of interest:
Hence, the annual interest rate on the deposit is 3.2%
