Answer 1

$\underbrace \text{Answer:}$

Question 1:

• Area of the circle: πr²

Question2:

$\sf{v + 4 = 4}$

$\implies \: \sf{v = 4 - 4}$

$\implies \: \bf{ \red{v = 0}}$

⛬ The value of v is 0.

Question 3:

• The sum of complementary angle is 90°

So,

(90-57)°

= 33°

⛬ The complement angle of 57° angle is 33°.

Question 4:

$\sf{0.003 \times 1000}$

$= \bf \red{3}$

⛬ The product of 0.003 and 1000 is 3.

Question 5:

$\sf{( - 21) \times ( - 30)}$

$= \bf \red{630}$

⛬ The product of (-21) and (-30) is 630.
