Answer:
Step-by-step explanation:
The lateral surface area is the product of half the circumference, and the slant height:
LA = πrh = π(11.4 cm)(23 cm) = 262.2π cm²
The total surface area adds the area of the base to that:
A = πr² +LA = π(11.4 cm)² +262.2π cm² = (129.96 +262.2)π cm²
A = 392.16π cm²
y=1/2x+2
m=(y2-y1)/(x2-x1)
m=(4-3)/(4-2)
m=1/2
y-y1=m(x-x1)
y-3=1/2(x-2)
y=1/2x-2/2+3
y=1/2x-1+3
y=1/2
