### Model Activity Task Class 10 Mathematics Part 2:

**1. Choose the correct answer and write it : **

The total interest of a principal in n yrs. at the rate of simple interest of *r *% per annum is *pnr*_{/25, }the principal will be

(a) Rs. 2*p *(b) Rs. 4*p *(c) Rs. *p/2 _{(d) Rs. }p/_{4}*.

**Answer the following questions: **

**2. **(i) If the height of two right circular cylinders are in the ratio 3 : 4 and perimeters are in the ratio 1 : 2, then find the ratio of their volumes.

**2. **(ii) AB and AC are two chords of a circle which are perpendicular to each other. If AB = 4 cm. and AC = 3 cm., then find the length of the radius of the circle.

**3. **If simple interest and compound interest of a certain sum of money for two years are Rs. 8400 and Rs. 8652, then find the sum of money and the rate of interest.

**4. **If the ratio of two roots of the quadratic equation a*x*^{2 }+ b*x *+ c = 0[ *a *≠ ]0 is 1 : r.

**5. **Prove that if any straight line passing through the centre of a circle bisects any chord, which is not a diameter, then the straight line will be perpendicular on that chord.

**6. **Height of a right circular cylinder is twice of its radius. If the height would be 6 times of its radius, then the volume of the cylinder would be greater by 539 cubic dcm., find the height of the cylinder.

### Model Activity Task Question Paper for Mathematics Part 1:

- Write the condition for the roots to become equal in the equation
*ax*(^{2 }+ bx + c = 0,*a, b, c*are real,*a*≠ 0). - The radius of a circle is 10 cm and the length of a chord is 12 cm. Then, calculate the distance between the chord and centre of the circle.
- If the ratio of the volumes of two cubes is 1 : 8, then find the ratio of the total surface areas of the two cubes.
- If the amount of Rs. 400/- for 2 years is 441 then find the annual rate of compound interest.
- If
*x*, 12,*y*, 27 are in continued proportion then find the values of*x*and*y*. - AB is a radius of a circle with centre O. C is a point on the circle. If ∠OBC = 60o then find the value of ∠OCA.
