9. The diagram shows a triangle inscribed in a circle with centre O. The lengths of the shorter sides of the triangle are 6 cm and 8 cm.
Work out the area of the circle.
Use π = 3.14.

25π

Step-by-step explanation:

let c = length of third side of triangle

since you are working with a right triangle you can find the third side by using the pythagorean theorem:  8^2 + 6^2 = c^2

64 + 36 = c^2

100 = c^2

c = 10

10 is also the diameter of the circle and radius is 5

A = π · r²

A = 5^2÷ (3 ^4 · x^24 · y^12)

A = 25π

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
