Answer:
26 cm³
Step-by-step explanation:
A cone is 1/3 the volume of a cylinder with the same dimensions
78/3= 26
Volume= 26 cm³
Answer:
Step-by-step explanation:
2(80*3)+2(3*200)+2(80*200)=33680cm

Step-by-step explanation:c
Note:
The equation for a circle with center at (h,k) and radius r is
(x-h)² + (y-k)² = r²
For the specified circle,
h=4, h=7.
From the diagram shown below, the radius, r, is determined from the Pythagorean Theorem as
r² = 3² + 3² = 18
Therefore the equation for the circle is
(x - 4)² + (y - 7)² = 18
Answer: (x - 4)² + (y - 7)² = 18
C- elemination or reduction
Method of elimination or reduction
Adding two equations is to obtain a new equation whose right (left) member is the sum of the right (left) members of the equations that are added together.
<span> 7X+5y=19
-7X-2y=-16.
</span> Adding two equations
3y=3 ---> y=1
then
7x+5(1)=19
7x=19-5
x=14/7=2
