Answer:
1.5×2.5/2=1.875.
Step-by-step explanation:
We all know that area of triangle is base into hight upon 2.
Answer:
V=pi x (r)^2 x h
V-volume r-radius h-height
V= pi x (3)^2 x 9
V= pi x 9 x 9
V= pi x 81
V= 254.47 (rounded)
Answer:
x=25 or x=0
Step-by-step explanation:
4x(x−25)=0
Step 1: Simplify both sides of the equation.
4x2−100x=0
For this equation: a=4, b=-100, c=0
4x2+−100x+0=0
Step 2: Use quadratic formula with a=4, b=-100, c=0.
x=−b±√b2−4ac over 2a
x=−(−100)±√(−100)2−4(4)(0) over 2(4)
x=100±√10000 over 8
x=25 or x=0
