Question 

(a) 

Find the perimeter of the triangle.

(b) The diagram shows a shape made from rectangles.

Calculate the area of the shape.

(c) The diagram shows a right-angled triangle ABC.

Calculate the area of the triangle.

(d) Calculate the volume of a sphere with diameter 5.25 cm.
[The volume, V, of a sphere with radius r is $V = \frac{4}{3}\pi r^3$.]

▶️ Answer/Explanation
Solution

(a) 21 cm
Simply add all sides: 10 + 7 + 4 = 21 cm.

(b) 118.1 cm²
Break into rectangles: (18.6×4) + (9.5×4.6) = 74.4 + 43.7 = 118.1 cm².

(c) 153.6 cm²
First find missing side: √(27.2²-24²) = 12.8 cm. Then area = ½×24×12.8 = 153.6 cm².

(d) 75.8 cm³
Radius = 5.25/2 = 2.625 cm. Volume = (4/3)π(2.625)³ ≈ 75.8 cm³.
