The diagonal of a rhombus are 12cm and 5cm. calculate its perimeter

A cone has a base radius of 8cm and height 11cm. calculate , correct to 2d.p, the curved surface area

In the diagram, \(\overline{PQ//RS}\) is a trapezium with QR//PS. U and T are points on \(\overline{PS}\) such that \(\overline{|PU|}\) = 5 cm,

\(\overline{|QU|}\) = 12 cm and ∠PUQ= ∠STR =90°. If the area of PQR = 20 cm\(^2\),

calculate, correct to the nearest whole number, the:

(a) perimeter; (b) area; of the trapezium

In the diagram, ∠POQ = 150 and the radius of the circle PSQR is 4.2cm. [take π = 22/7]

What is the length of the minor arc?

In the diagram, ∠ZWZY and WYX are right angles. Find the perimeter of WXYZ.
