22400 because the rule for rounding is to round based off of the number next to the place you want to round to. You're rounding to the nearest hundreds so you look at the tens place. If the number is 4 or less you round down, and if the number is 5 or more, you round up. The number in the tens place is 6 so you round up to get 22400. Hope that this answer and explanation help!
Answer:
A. 68 units2
Step-by-step explanation:
First of all to solve this problem we have to know the formula to calculate the surface area of the cone
A = area
r = radius = 4
L = 13
π = pi
A = π*r² + π*L*r
we replace with the known values
A = π * (4u)² + π * 13u * 4u
A = 16π u² + 52π u²
A = 68π u²
The surface area of the cone is 68π u²
No, the functions shown are not inverses because the inverse for f(n)=-(n+1)^3would be f^−1(n)=−3√n−1.
