Find the area of a circle with radius, r = 88cm.
Give your answer rounded to 3 SF.

find using calculator yourself:))

Step-by-step explanation:

pi x r x r = pi x 88 x 88 = answer

243

Step-by-step explanation:

Area of a circle = pir^2

So, pi x 88^2

= 243 (3 s.f.)

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.
