Considering f(x)= y. You find what y value correlates with the x value so f(0)=4 brong that the line with y=4 the x is 0. f(-2)= 2 as the line where x=-2 has y=2
Answer:
The arc measure of BC is 64
Step-by-step explanation:
1. Calculate the full circumference of the circle
C=2pir
=2pi(18)
=36pi
2. Figure out the arc measure
arc length/circumference=arc measure/degrees in a circle
14pi/36pi=arc measure/360 (solve for arc measure)
14pi/36pi *360=140
The measures of BC and CA add up to the measure of BA
mBC +76=140
BC=64
Step-by-step explanation:
42/154
21/77 ( divide by 2)
The radius of the cylinder is 6 cm, so the area of one base will be
A = π·r²
A = π·(6 cm)²
A = 36π cm²
The area of 2 bases will be double this, or
A = 72π cm² ≈ 226.19 cm²
It appears the appropriate choice is
226.08 cm²
