Step-by-step explanation:
surface area of cylinder is
2×pi×r (h+r)
2×22/7×2 (4+2)
88/7 (4+2)
75.4 cm square
Slope is rise/run, or y/x. So y from zero to 4 is 4, and x from -2 to zero is 2. and 4/2=2, so the slope is 2
Answer:
15
Step-by-step explanation:
Where n represent no.of sides
(2n-4)90=2340
180n-360=2340
180n=2340+360
180n=2700
n=15
