Section C

11. The sum of first 20 terms of an AP is 400 and sum of first 40 terms is 1600. Find the sum of its first 10 terms.

12. Draw a line segment AB of length 8 cm. Taking A as centre, draw a circle of radius 4 cm, and taking B as centre draw another circle of radius 3 cm. Construct tangents to each circle of radius centre of the other circle.

OR

Draw a line segment AB of length 7 cm. Taking A as centre, draw a circle of radius 3 cm and taking B as center, draw another circle of radius 2 cm. Construct tangents to each circle from the centre of the other circle.

13. Building Sheep Pens : Darsh and Darpan are fencing off a large rectangular area to build some temporary holding pens. To prep the males, females, and kids, they are separated into three smaller and equal-size pens partitioned within the large rectangle.

(i) If 384 ft of fencing is available and the maximum area is desired, what will be the dimensions of the larger, outer rectangle?

(ii) What will be the dimensions of the smaller holding pens?

14. Rainfall is one of the most commonly shared experiences on Earth. Rainfall is also necessary, since it provides water to plants and ultimately fills rivers. Because rainfall is both a needed resources and a threat, it is important to better understand this natural phenomenon. The most common rainfall measurement is the total rainfall depth during a given period, expressed in millimeters (mm). For instance, we might want to know how many millimeters of rain fell over the course of 1 h, 1 day, 1 month, or 1 year.

The rain water from 22m #20m roof drains into cylindrical vessel of diameter 2 m and height 3.5 m.
(i) If the rain water collected from the roof fills 4th/5 of cylindrical vessel then find the rainfall in cm.
(ii) If rainfall is the 1.5 cm find the hight of water collected in cylindrical vessel.
