Answer: area= 4.7
Area=pi*r^2=3.14*1.5=4.71=4.7 (nearest tenth)
Answer:
You take 6% of a number and the resulting number is 27.
To do this you need to change the percent into a fraction.
6% = 6/100
This is the number you need to multiply to the number you need to find, A.
6/100 A = 27
Solve for x
6 A = 27x100
A= 2700/6
A = 450
Check your answer:
6/100 (A) = 27
6/100 (450) = 27
(6x450) /100 = 27
2700 / 100 = 27
27 = 27
Step-by-step explanation:
let the number is 10x + 3.
then sum of its digits = x + 3.
from given condition, we have
x+3 = (1/7)* (10x + 3)
=> 7x + 21 = 10x + 3
=> 3x = 18
=> x = 6
therefore the number is 63.
