Answer:
314 square cenntimeters
Step-by-step explanation:
Area of the circular cross-section of the pipe = πd²/4
Given that;
d = 20cm
Area = π(20)²/4
Area = 400π/4
Area = 100π
Area = 100(3.14)
Area = 314cm²
Hence the area of the circular cross-section of this pipe is 314 square cenntimeters
Answer:
The amount of interest to be paid is $105
Step-by-step explanation:
To find how much interest that will be paid, we will follow the steps below;
Simple Interest = PRT / 100
where p is the principal, R is the rate and T is the time in years
from the question given
principal P = $1000
Rate R = 3.5
and time T = 3
substitute the values into the formula above
Interest = $1000×3.5×3 / 100
=$10×3.5×3
=$105
Interest = $105
The amount of interest to be paid is $105
Answer:
w= p-2l divided by 2 or w= p/2 -l. This is the letter l, not 1.
Step-by-step explanation:
Subtract both sides by 2l to isolate for 2w. Then, you have 2w= p-2l. You have to make w to the lowest terms or make it a coefficient of one. To do that, you have to divide everything by 2. 2w divided 2 is w, p/2 is p/2, and length is -2l divided by 2 which is -l. You could also just leave it as 2l-p that whole expression gets divided by 2. Hope this helps!
The answer is 53 that is what i got
650 or 650x?
If 650:
650/60 is 10 and 5/6 because 650/60=10 and 5/6
If 650x:
Do the same thing but multiply first. For example if x = 6 then 650*6=3900 and then 3900/60=65
