Answer: Area of circular plate is 36.5 square inches
Step-by-step explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Circumference of circular plate = 21.4 inches. Therefore
2 × 3.14 × r = 21.4
6.28r = 21.4
r = 21.4/6.28
r = 3.41 inches
The formula for determining the area of a circle is expressed as
Area = πr²
Area of circular plate = 3.14 × 3.41² = 36.5 square inches
The answer: Time= Distance divide Speed.
Speed= 675,000 divide 900= 750 minutes. Convert that to hours and that leaves you with 12 hours and a half. If these questions are bothering you, just revise them- they’re speed distance time equations and i’d be blessed if they come up in my maths exam tomorrow.
Answer:
You use the formulas for the shapes
Cylinder= 2×π×r×h+2×π×r² π×r²×h
Cone=
π×r²×
Square Prism= 2×a²+4×a×h a²×h
↑a=base edge
Step-by-step explanation:
Surface Area Volume
Cylinderical Head ≈282.74 ≈314.16
Conical Hat ≈170.13 ≈78.54
Right Cylinder Torso ≈471.24 ≈785.4
Right Cylinder Arm ≈56.55 ≈25.13
Square Prism Leg =224 =192
Since z is GREATER THAN two angles in the triangle it must be obtuse..
meaning it is GREATER THAN 90 degrees this means that the other two angles cannot equal 90 degrees they have to be less
m∠X + m∠Y < 90°
Answer:
m = (2 - (-1)) / (0 - (-1)) = 3/1 = 3
y = 3 * (x - 0) + 2
y = 3 * x + 2
