c. 120 cm
d. 120cm
e. 14cm
​

Answer 1

Answer:

a) 28.26 cm

b) 226.98 m

c) 45,238.93 cm

d) 45,238.93 cm

e) 615.75 cm

Step-by-step explanation:

How to find the area of a circle:

πr² (pi is 3.14...)

a) 3² = 9

9π ≈ 28.26

b) 8.5² = 72.25

72.25π ≈ 226.98

c) 120² = 14,400

14,400π ≈ 45,238.93

d) 120² = 14,400

14,400π ≈ 45,238.93

e) 14² = 196

196π ≈ 615.75
