Use pi times r^2. 4^2=16. 16 pi = 50.2654824574. round as needed. CLOSEST INCHES WOULD BE 50!!
The answer is 10.43$
Step by step:
30 / 4 = 7.5, so 7.5 pounds is needed
7.5 x 1.39 = 10.425 which is rounded to 10.43$
Answer:
Perimeter = 30 yd
Area = 43.301 yd²
Step-by-step explanation:
The Triangle has three equal sides of 10 yd each. It is therefore an equilateral triangle with equal angle measuring 60° each.
Thus:
✔️ Perimeter = sum of all sides = 10 + 10 + 10 = 30 yd
✔️Area can be found using, A = ½*ab*Sinθ
Where,
a = 10 yd
b = 10 yd
θ = 60°
A = ½*10*10*Sin 60
A = 43.301 yd² (3 decimal places).
Answer:
D) Multiplication should be performed before addition
Rational numbers can be negatives and positives. When negative, they are called integers. If you add one negative number that is higher than the positive number, it can be negative. For instance: -63+3= -60
