I need help on this please

circumference =2πr=2× 7 22  ×28=22×8 =176 cm

Area =πr 2 = 7   22 ×28×28=88×28 =2464 cm 2

circumference=176 cm

Area= 2464 cm 2

What she said

Step-by-step explanation:

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
