Uhhh just look at the photo I guess Work out the area of this circle.
Take pi to be 3.142 and write down all the digits given by ur calculator

314.2 cm²

Step-by-step explanation:

The formula for the area of a circle is πr², so since the radius is 10, just multiply 100 × π, which is 314.2, since the problem told you to use 3.142 for π.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
