Answer:
1107
Step-by-step explanation:
72+ (33+12)23
= 72 + (45)23
=72+ 1035
=1107
We know that
surface area of the cone (SA)=pi*r²+pi*r*l
where
r is the radius
l is the slant height
SA=306*pi cm²
diameter=12 cm
r=12/2----> r=6 cm
SA=pi*r²+pi*r*l--------> [SA-pi*r²]=pi*r*l----> l=[SA-pi*r²]/[pi*r]
l=[306*pi-pi*6²]/[pi*6]---> [306*pi-36*pi]/[6*pi]---> 45 cm
the answer is
<span>the length of the slant height is </span>45 cm
Answer:
(2,2)
Step-by-step explanation:
first graph the line y=2 (draw a horizontal line through 2 on the y-axis
then graph the line y=1/2x +1 ( plot the point (0,1) and then move up 1 and right 2 or down 1 left 2
then find the point that the lines intersect. That is the solution for the system
