### Answer Key

**1. B
**The diagonals of a square intersect perpendicularly with each other so each angle measures 90

^{o }x =90

^{o}

**2. B
**a+b+c+d = ?

The sum of angles around a point is 360

^{o }a+b+c+d = 360

^{o}

**3. C
**The sum of angles around a point is 360

^{o }d+300 = 360

^{o }d = 60

^{o}

**4. D
**Two parallel lines(

*m*& side AB) intersected by side AC

a= 50

^{o }(interior angles)

**5. B
**The square with 2 cm side common to the rectangle apart from 4cm side

Perimeter = 2+2+2+4+2+4 = 16 cm

**6. C
**In the figure, we are given a large circle and a small circle inside it;

with the diameter equal to the radius of the large one. The diameter of the

small circle is 4 cm. This means that its radius is 2 cm. Since the diameter

of the small circle is the radius of the large circle, the radius of the large

circle is 4 cm. The area of a circle is calculated by: пr

^{2}where r is the

radius. Area of the small circle: п(2)2 = 4п Area of the large circle: п(4)

^{2}2 = 16п

The difference area is found by:

Area of the large circle – Area of the small circle = 16п – 4п = 12п

**7. D**

Perimeter of a shape with two squares and triangle ABC.

Perimeter = 8.5+8.5+6+6

Perimeter = 29 cm.

**8. C **

Large cube is made up of 8 smaller cubes of 5 cm sides.

Volume = Volume of small cube x 8

Volume = (5 x 5 x 5) x 8, 125 x 8

Volume = 1000cm^{3}

**9. B
**Volume= Volume of large cylinder – Volume of small cylinder

(Volume of cylinder = area of base x height)

Volume= (п 12

^{2}x 10) – (п 6

^{2}x 5), 1440? – 180п

Volume= 1260п in

^{3}

answer to question five should be 18, you forgot to include the 2cm outer side of the rectangle

Divide the figure into a square and a rectangle – perimeter of the square – 3 X 2 = 6 note 3 sides are included in the perimeter. Upper rectangle 2 X 4 = 8 + 2 = 10 total perimeter = 10 + 6 = 16

what angel said is so true, i cant believe u guys made such a silly mistake

Try again – the question asks for the PERIMITER – 3 sides of the square – 2 + 2 + 2 = 6; 2 sides of the rectangle – 4 + 4 = 8; 1 side of the rectangle (top) = 2

6 + 8 + 2 = 16

Please in no 6 ,42 -22 is 20,so how comes about 16 and how did u get 122 in no 10

The answers are correct – I have updated and expanded the solutions – also the п symbol wasn’t displaying properly – thanks!

Love this. Super helpful!

In #9, since it is a cylinder; shouldn’t you use Pi in calculating the area of the base??

hi – yes the answer does use pi – the web rendering is a little funny tho – looks like an ‘n’ but is is pi – e. g. Volume= (п 122x 10) – (п 62x 5), 1440? – 180п
