Step-by-step explanation:
The area of the shaded portion is calculated as
area of outer sector - area of inner sector
= (πR² - π r²) × ( R is the outer radius, r is the inner radius )
= (π × 14² - π × 7² ) ×
= (196π - 49π ) ÷ 6
= 147π ÷ 6
≈ 77 cm² ( nearest whole number )
Mr. Jenson needs 250 square tiles of dimensions 12 cm which cover 3.6 square metres walkway.
What is the area of Square?
The area of a square is the product of the length of each side with itself, i.e. Area A = s x s where s is the length of each side of the square.
Mr. Jenson wants to tile 3.6 sq. meters or 36000 sq. cm.
Total number of tiles is 250.
Area of tile = = 36000/ 250 = 144 sq. cm
s X s = 144 sq. cm
s = cm
s = 12 cm
Thus, Mr. Jenson needs 250 square tiles of dimensions 12 cm which cover 3.6 square metres walkway..
