Answer: h = (S - 2πr²) / 2πr
Step-by-step explanation:
Since we are given that
S = 2πrh + 2πr²
Subtracting by 2πr² on both sides we get
S - 2πr² = 2πrh
Dividing by 2πr on both sides we get
(S - 2πr²) / 2πr = h
So
The final equation is
h = (S - 2πr²) / 2πr
Oh okie so cute lol I love you
Answer:
the above is a function
Step-by-step explanation:
function is a mapping from a set A to B, which associative every element of A with unique image in B.
Here, f(-3)=6, f(-5)=6
f(3)= -2, f(-5)=1
all elements have image.
so this is a function.
<u>Answer:</u>
The correct answer options are A, B, C and D.
<u>Step-by-step explanation:</u>
A. Leg-angle (LA):
According to this theorem, if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.
B. Hypotenuse-leg (HL):
If any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
C. Hypotenuse-angle (HA):
If the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.
D. Leg-leg (LL):
If any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
Answer: 2) 1767.1
Step-by-step explanation:
For a sphere, V=(4
/3)πr^3. A diameter is 2r. Thus the radius of the circle is 7.5 inches. Thus, the volume is about 1767.15.
Hope it helps <3
