Step-by-step explanation:
21 times 6 + 7 times 9 = 189
Answer:
Right triangle.
Step-by-step explanation:
We are asked to determine whether the given side lengths are sides of a right triangle or not.
We know that side lengths of a right triangle are Pythagoras triplets. The square of the longest must be equal to sum of squares of other sides.
Let us check sides of our given triangle.



Since both sides of equation are equal, therefore, the given side lengths are sides of a right triangle.
Volume=(4/3)pi(r^3)
radius=1/2diameter
d=36
radius=1/2 36
radius=18
subsitute
volume=4/3 pi 18^3
volume=4/3 pi 5832
volume=23328/3 pi
volume=7776pi
aprox pi to 3.14
volume=7776 times 3.14
volume=24416.64
answer is 24416.64 yd^3
Answer:
z=12
Step-by-step explanation:
divide by 1/2 to get the variable z by itself
Radius = 9m
Diameter = 18 m
Area = 254.34 squared m
Circumference = 56.52 m
I’m guessing is asking for the circumference because it says around
