Answer:
perimeter of circle=2πr
16=2πr
r=16/2π=8/πcm
now.
area of circle=πr²=π(8/π)²=π×64/π²=64/(22/7)=64×7/22=20.36cm²
Answer:
8.727
Step-by-step explanation:
Since the below edge, d = 15 cm, and the height, h = 12.2 cm, we will use the Pythagorean theorem to find the distance r.




Answer:
so, 15 divided by 3 is 5. so the constant of proportionality is 5. and 60 seconds for the minute, divided by 5 is................12.
if this is wrong im sorry. Hope i helped!
Answer:
m = 1/4
Step-by-step explanation:
slope = rise / run
rise = 1 (red arrow)
run = 4 (dotted line)
<h2><u>Solution</u> :-</h2>
Given : Radius of cylinder = 8 m
Height = 4 m
Volume of cylinder = πr²h cu. units
= 22/7 × 8 × 8 × 4 m³
= 804.57 m³ (approx.)
Curved surface area = 2πrh sq. units
= 2 × 22/7 × 8 × 4 m²
= 201.14 m² (approx.)
Total surface area = 2πr(r + h) sq. units
= 2 × 22/7 × 8 (8 + 4) m²
= 2 × 22/7 × 8 × 12 m²
= 603.43 (approx.)
