SA = 2bA (base area) + LA (lateral area)
bA = r^2*pi = 13^2pi = 169pi cm^2
LA = 2r*pi*h = 2*13*pi*88,4 = 2298,4pi cm^2
SA = (2*169pi)+2298,4 pi = 338pi+2298,4pi = 2636,4pi
A
given the 2 equations
2x + y = - 2 → (1)
x + y = 5 → (2)
subtract (2) from (1) term by term to eliminate y
(2x - x ) + (y - y ) = (- 2 - 5 )
x + 0 = - 7 ⇒ x = - 7
substitute x = - 7 in either of the 2 equations and solve for y
(2) : - 7 + y = 5 ( add 7 to both sides )
y = 5 + 7 = 12 → A
Answer:
5
Step-by-step explanation:
You will multiply 1/3 by 3. This equals 1. 5^1 equals 5.
