Answer:
(ab)^d+e
Step-by-step explanation:
use the law of powers
a^b + a^c = a^b + c
Area = π.R² AND CIRCUMFERENCE = 2π.R
Let's calculate R (radius):
452.16 = π.R² → R² = 452.16/π → R² = 143.92 And R = √143.92 →R = 12 m
CIRCUMFERENCE = 2π.R = 2π.12 = 24 π = 75.39 84 (Answer D)
Answer:
0.35*4=1.40
Step-by-step explanation:
Think of doing 35*4 but dividing the result by 100, or 2 decimal places to the left:
35*4 = 35*2*2 = 70*2 = 140
140/100 = 1.40
So, 0.35*4=1.40
