Answer:
8/20 + 5/20 = 13/20
Step-by-step explanation: You would have to multiply the numerator and denominator of 2/5 by 4 to get 8/20 and multiply the numerator and denominator of 1/4 by 5 to get 5/20, equaling to 13/20.
It would be 2*(5^2)
(2 multiply to (5 rise to the power of 2))
Hope that help.
Answer:
200π; 628
Step-by-step explanation:
The volume of a cone can be found with the formula:
V=πr^2(h/3)
Now, we can plug the values that we know in.
Height is 6
Radius is 10
That said, our equation is now:
V=π10^2(6/3)
Simplify.
V=π100(2)
V=200π
Or, using 3.14 for pi it would be:
200(3.14)
628
Answer: 1,162.9 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a square pyramid: 1/3 x base area x height
Where
base area = base side length ^2
Replacing with the value given:
Base area = 15.9^2
base area : 252.81 cm2
Back with the volume formula:
V = 1/3 x base area x height
Replacing with the values given and solving for V (volume)
V = 1/3 x 252.81 x 13.8 = 1,162.9 cubic centimeters
