A patio made of concrete patio stones surrounds a circular pool. Helen wants to paint the concrete with a sealant to protect it. One can of sealant covers 175 ft 2. What is the area of the patio, to the nearest square foot? (Use 3.14 for π )

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

m∠a is 90°

m∠b is 40°

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
