The circle with center C was used as a model for a swimming pool. The length BC of is 10 m. What is the area of the pool?

314.2 m²

Step-by-step explanation:

Given:

BC = radius (r) = 10 m

Required:

Area of the pool

Solution:

The area of the pool = area of circle = πr²

Plug in the values

Area = π*10²

Area = 314.159265 = 314.2 m² (to nearest tenth)

Area of the pool = 314.2 m²

Step-by-step explanation:

10/2 = 5*3.14=15.7

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.
