Question

please could someone help

Answer 1

arc length =11 cm

perimeter = 25 cm

area= 38.5 cm^2

Answer 2

Answer:

As you can see it's a quadrant, that is One fourth of a circle so it's area will also be 1/4 th of the circles area

Area = 1/4 πr² = 1/4 × 22/7 × 49 = 38.5 cm²

The arch length will be 1/4 th of the circle

Arc length = 1/4 2πr = 11cm

Now for perimeter, there's a catch, perimeter means sum of all sides of a geometric shape, so for this circle perimeter is sum of Arc length and the two radii

Perimeter = Arc length + 2r = 25 cm

(I apologise if there are any calculation mistakes)
