I believe its b because theres a large range of scores
I mean the answer is 34 sorry for the mistake
A function has only one y-value for each x-value. If you find a set that has an x-value used more than once, it is not a function, because that x-value is now paired with more than one y-value.
The fourth answer is the only one that has the same x-value used more than once.
Side note: Don’t worry if a y-value is used more than once. That’s totally fine. It’s all about the x-values.
Answer: 12.
Step-by-step explanation: Use Pythagorean Theorem. We that a = 9, b = ?, and c = 15. Plugging that in gives us 9^2 + b^2 + 15^2. Solving for b gets us b^2 = 144. Taking the square root of both sides gets us b = 12.
we know that
Volume of a cone=(1/3)*[B]*h
where
B is he area of the base
h is the height
Find the volume of a cone in each case
case a) Raj
h=3 cm
diameter=5 cm
so
radius r=5/2=2.5 cm
Area of the base B=pi*r²
B=pi*2.5²
B=6.25*pi cm²
V=(1/3)*6.25*pi*3=6.25*pi cm³
case b) Amit
h=4 cm
r=3 cm
Area of the base B=pi*r²
B=pi*3²
B=9*pi cm²
V=(1/3)*9*pi*4=12*pi cm³
case c) Parul
h=7 cm
Area of the base B=4*pi cm²
V=(1/3)*4*pi*7=(9.33)*pi cm³
case d)Lara
h=6 cm
Area of the base B=3*pi cm²
V=(1/3)*3*pi*6=(6)*pi cm³
therefore
the answer is
Parul
