Length of distance of arc = 2πr × (∅/360)

∅ = 1/60 × 360 = 6⁰

Length = 2 × 22/7 × 3960(6/60)

Length = 44/7 × 3960 × 1/10

Length = 44/7 × 396

Length = 2489.142 cm

Hi there!

We can find the area of a triangle with the formula:
area = 0.5 \times base \times height

Filling in this formula gives us the following answers.

Triangle 1
area = 0.5 \times 5 \times 8 = 20

Triangle 2
area = 0.5 \times 7 \times 9 = 31.5

Triangle 3
area = 0.5 \times 16 \times 12 = 96
