Step-by-step explanation:
Semicircle Area and Perimeter
Area (A)
6.2832in²
A = πr²/2 = 2 * π [in²] ≈ 6.2832 [in²]
Perimeter (L)
10.2832 in
L = πr + d = 2 * π + 4 [inch] ≈ 10.2832 [inch]

Answer: -3a^2 + 11a
Step-by-step explanation:
4a - (a x 3a) + 7a - Multiply first to get 4a - 3a^2 + 7a
4a - 3a^2 + 7a - Add like terms (a terms) to get -3a^2 + 11a
So the answer in -3a^2 + 11a
