Find the area of the circle. Use 3.14 for it. E d = 10 cm A = [?] cm2 A=7tr2
2 answers:
Answer: d=10cm
According to the formula i.e. A=πr²
first we need 'r'
as r=d/2
hence, r= 10cm/2
r=5cm
put r=5 in formula
=3.14(5cm)²
=3.14×25cm²
=78.5cm²
Answer:
A=(78.5)cm²
Step-by-step explanation:
d=10
r=10/2=5
A=πr²
A=3.14*5²
A=3.14*25
A=78.5cm²
