### 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

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

The line between the square and the rectangle isn’t counted for perimeter, perimeter is the amount of units around the OUTSIDE. Since the square and rectangle are connected, try thinking of them as one big rectangle and forget about the line in between.

Correct – the bottom square has 2 cm each side on 3 sides (2 + 2 + 2 = 6). The top rectangle has 2, 4 cm sides (4 + 4 = 8) and 1, 2 cm side. So the total is 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!

102°-2x +78°=180°

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

I understand how you got the answer in question 5, however the way it is displayed is unclear.

It is not clear that the number 4 is attached to just the rectangle and not to the line as a whole.

This means there are two interpretations of the figure.

1) 4*2+2*2 = 12

2) 2(4+2) + 2*2 = 16

Thanks! this was super helpful!
