20. square-10+10=20x2=400m^2
circle- 3.14x10^2=3.14x100=314
400-314=86
86m^2
21.i don't get 21 sorry
Let us use 360 days for the 1-year term.
principal = 1,200
interest rate = 8% unless otherwise stated, this rate is per annum or annual rate.
term = 240 days
Simple Interest = Principal * interest rate * term
S.I = 1,200 * 8% * 240/360
S.I = 1,200 * 0.08 * 0.667
S.I = 64.032 rounded off to 64
The interest due 1200 at 8% rate is 64 in 240 days.
Hope that helps and feel free to ask me more questions :)

Answer:
h = s / π.r²
Step-by-step explanation:
the given equation is s = π.r².h
Now if we have to calculate the value of h from the given formula then we will solve it so that h remains alone on one side of the equation.
This only possible when we divide term on both the sides by π.r²
s/π.r² = π.r².h/π.r²
h = s / π.r²
Therefore h = s / π.r² is the right option.
3 ways to express 3 to the 5th power as the product of powers
First expression
=> 3 x 3 x 3 x 3 x 3 - In this expression, we multiplied 3 5 times and the product is 243
Second expression
=> 3 ^ 5, in where ^ read as raised to the power, the product is also 243
Third expression
=> 3^2 x 3^3
=> (3 x 3) x (3 x 3 x 3)
=> 9 x 27, the product also equals to 243.
