Answer:
19cm
Step-by-step explanation:
x * 5x = 1805
5x ^2 = 1805
x^2 = 361
square root of that is 19
(1) circumference of a circle = 2π.R
(2) area of a circle = π.R²
Area = 452.16 m² (given), so we can calculate the radius:
452.16 = π.R²
452.16/π = R²
143.92 = R² → R =√143.92 ≈ 12 m
Having R = 12, now we can calculate the circumference :
circumference of a circle = 2π.R = 2.π.12 = 75.41 m
Answer is B: 150
write two equations
r+s=190
4r+3s=720
solve by substitution
the get r=150 s=40
Well that would be 8 apples in 4 bags so there’s 6
answer: 6
Answer:
It's the first one. (m + n - 1) sqrt p
Step-by-step explanation:
We can combine m sqrt p and n sqrt p, resulting in m + n, and combine - sqrt p to become (m + n - 1)sqrt p
