1. Calculate the area of a major segment whose chord subtends angle of 85 at the centre of a circle of radius 3cm. 2. A solid cone has a base radius of 3cm and a vertical height of 21cm. Calculate its volume.

2.193 and

Step-by-step explanation:

Area of Segment = πr²θ/360 -½r²sinθ

=π*3²*85/360-½*r²sin85

= 2.193cm²

volume of cone= ⅓πr²h

=⅓*π*3²*21

=198 cm³

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
