Find the area of each circle. Round to the nearest tenth. Use 3.14 or 22/7 for Pi. r = 7.1 m

158.3 m² (to nearest tenth)

Step-by-step explanation:

Given

Area of a circle =

⇒ area = 3.14 x 7.1²

⇒ area = 158.2874

⇒ area = 158.3 m² (to nearest tenth)

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
