Question

Diameter of circular garden is 9.8 metre. Find the area and perimeter

Answer 1

Answer: area=75.46$m^{2}$

perimeter=30.8m

Step-by-step explanation: d = 9.8 m

r = 9.8 ÷ 2

r = 4.9 m

area of a circle= π$r^{2}$

= 22×4.9×4.9÷7

= 75.46

the area of the circle is 75.46$m^{2}$

perimeter of a circle = 2πr

=2×22×4.9÷7

=30.8m

the perimeter of the circle is 30.8m

Answer 2

Answer:

area=75.46

perimeter=30.8

Step-by-step explanation:

RADIUS=9.8/2=4.9

area=π*r²

=22/7*4.9*4.9

=75.46

perimeter=2*π*r

=2*22/7*4.9

=30.8
