Step-by-step explanation:

Pakipicturan po mabuti ung task 1 para makita ko po ung given. malabo po kasi

Task 1

Number 1

r = 30cm

s= 13 cm

Area of a square = a^2

Area of a square = a^2As= 13^2

^2As= 169cm^2

cm^2Area of Circle = πr^2

cm^2Area of Circle = πr^2Ac= π x 30^2

cm^2Area of Circle = πr^2Ac= π x 30^2Ac= 2827.43cm^2

Area of circle not painted = Ac - As

Area of circle not painted = Ac - AsA = 2827.43 - 169

A = 2,658.43 cm^2

Task 2

Number 1.

The 4 sided figure is square.

Side of the square = 7 m

Area of the square = s^2

As = 49 sq. m

Area of circle = πr^2

r= 3.5m

Ac = 38. 47 sq. m

Area of Shaded region = As - Ac

Asr= 49 - 38.47

Asr= 10.53 sq. m

Number 2

if the given is l=5m ; w=5m; r= 2.5 (malabo po ung given)

Area = l x w + (πr^2)

Area = (5 x 5) + (3.14 x 2.5x 2.5)

Area = 44.625 sq. m
