Answer:
see explanation
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius, here r = 9, thus
A = 4π × 9² = 4π × 81 = 324π ≈ 1017.9 units²
3:1 =300%
2:3:5 =50%
1:4 =25%
1:2:5 =62.5%
First one is C,
Second is A
Third is C pretty sure
Fourth is D
If it weighs 1 3/4 lb’s then that’s it’s total weight…
The toy is 2(x)-20, x is 100, being the toy car. So 2(100)= 200 -20 =180. The cost of the toy is $180
