The minute hand when moving is swiping a sector
The arc length is given 23.5 inch the angle swiped is 52 degree
we have to find radius
length of arc = 2pi r( theta )/360
23.5 = 2* 3.14 * r ( 52/360)
23.5 = r(0.907)
r= 23.5/ 0.907
r=25.90 inches Answer
Answer:
112 cm²
Step-by-step explanation:
The surface area is the sum of the area of all the 6 faces, that is
area = area of 2 purple + area of 2 green + area of 2 orange
= 2(4 × 8) + 2(2 × 8) + 2(4 × 2)
= (2 × 32) + (2 × 16) + (2 × 8)
= 64 + 32 + 16
= 112 cm²
Answer:
Volume of a cylinder is πr²h
Where
r is the radius
h is the height
Volume = 154cm³
radius = 3cm
height = ? cm
154 = π × 3² × h
154 = π × 9 × h
154 = 9πh
divide both sides by 9π
h = 154/9π
h = 5.4cm
Height is 5.4cm
