Step-by-step explanation:
diameter=7 inches
Area of the circle= π(7/2)² inches²
=38.465
38.5 inches²
Answer:
38.5 inches
Step-by-step explanation:
r = 1/2d
r = 1/2 × 7
r = 3.5
[tex] \boxed{ \bold{formula = \pi \: {r}^{2} }}[/tex]
= 3.14 × 3.5 × 3.5
= 38.465 inches
Find its area to the nearest tenth
38.465 inches
= 38.5 inches
