Answer:
area of circle=πr²=π50²=2500πunit²
Answer: Area of circular plate is 36.5 square inches
Step-by-step explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Circumference of circular plate = 21.4 inches. Therefore
2 × 3.14 × r = 21.4
6.28r = 21.4
r = 21.4/6.28
r = 3.41 inches
The formula for determining the area of a circle is expressed as
Area = πr²
Area of circular plate = 3.14 × 3.41² = 36.5 square inches
38 4/7 = 270/7
% (percent) means per hundred (1/100)
so, (270/7)% is same thing as 270/700 or 27/70.
Answer: 270/100 or 27/70
Step-by-step explanation: 2 per hour and per person because 8 x 5 is 40 so 400 divided by 40 equals 10 so then 10 divided by 5 is 2 so 2 per hour
8b+12-b=8+7b+4
7b+12=12+7b
-7b
7b-7b+12=12
-12 -12
0= 12-12
0=0
