Question

Diameter of a circular garden is 9.8 m . Find it's area

Answer 1

Answer:

Step-by-step explanation:

diameter = 9.8m

radius = 4.9 m

Area = πr²

        = $\frac{22}{7}$ x4.9 x 4.9

        = 75.46

Answer 2

Answer:

diameter = 9.8m

radius = 9.8/2 = 4.9m

$area \: of \: circuar \: garden \: = \: area \: of \: cicle \\ \: \: \: \: \: \: \: \: \: \: = \pi {r}^{2} \\ \: \: \: \: \: \: \: \: \: \: = \frac{22}{7} \times 4.9 \times 4.9 \: \: \: \: m \times m \\ \: \: \: \: \: \: \: \: \: \: = 22 \times 0.7 \times 4.9 \: \: {m}^{2} \\ \: \: \: \: \: \: \: \: \: \: = 75.46 \: {m}^{2}$

Area of Cirular Garden = 75.46 sq.m
