Question

find the perimeter of square of 63 m.

Find the area of circle with radius 7 cm..​

Answer 1

Answer:

(☞ perimeter of square of 63 m

Using the formula

Using the formulaP=4a

Using the formulaP=4aSolving fora

Using the formulaP=4aSolving foraa=P/4

Using the formulaP=4aSolving foraa=P/4solving for a "

Using the formulaP=4aSolving foraa=P/4solving for a "a = p/4

Using the formulaP=4aSolving foraa=P/4solving for a "a = p/4 = 63/4

Using the formulaP=4aSolving foraa=P/4solving for a "a = p/4 = 63/4 = 15.75 m.

(☞ area of circle with radius 7 cm

Area of circle = πr²

Area of circle = πr²Radius = 7 cm

Area of circle = πr²Radius = 7 cmtherefore ,

Area of circle = πr²Radius = 7 cmtherefore ,area = 3.14 × (7)²

Area of circle = πr²Radius = 7 cmtherefore ,area = 3.14 × (7)² 153.86 cm²
