1. Find the perimeter of the square then the circumference of the circle then subtract the circle from the square.
Area of square=length of side squared=9.8^2=96.04.
Area of circle=(pi*radius)^2=((22/7)*(9.8/2))^2

2. Area of circle=pi*r squared
38.5=((22/7)*r)^2
Solve for r
Square root of 38.5/(22/7))=r
calculate area using above formula

In a class test(3+) marks are given for every correct answer and (-2) marks are given for every incorrect answer (-2) marks are

Diano4ka-milaya [45]

The number of incorrect answers made by Radhika is 8; the number of incorrect answers made by Mohini = 13

<h3>How to solve algebra word problems?</h3>

We are given;

Marks obtained for 1 right answer = +3

Marks obtained for 1 wrong answer = −2

(i) Marks scored by Radhika = 20

Marks obtained for 12 correct answers = 12 × 3 = 36

Marks obtained for incorrect answers = Total score − Marks obtained for 12 correct answers = 20 − 36 = −16

Marks obtained for 1 wrong answer = −2

Thus, number of incorrect answers = (−16) ÷(−2) = 8

Therefore, the number of incorrect answers made by Radhika = 8

(ii) Marks scored by Mohini = −5

Marks obtained for 7 correct answers = 7 × 3 = 21

Marks obtained for incorrect answers = Total score − Marks obtained for 12 correct answers = − 5 − 21 = −26

Marks obtained for 1 wrong answer = −2

Thus, number of incorrect answers = (−26) ÷ (−2) = 13

So, the number of incorrect answers made by Mohini = 13
