Find mPRT. P 649U 42° R s

Mathematics
1 answer:
Mkey [24]2 years ago
3 0

Answer: 296 degrees

Step-by-step explanation:

Arc PRT is just the entire circumference - arc PT.

Since the 64 degree angle is a central angle, arc PT measures 64 degrees.

So arc PRT = 360 degree - 64 degree = 296 degrees.

The lateral area of a cylinder is 325 pi inch^2. The radius is 13 in. Find the surface area and volume. Please show all work!!!
USPshnik [31]
Answer:

Surface area =  663π in².
Volume = (676/3)π in² ≈ 225.33 π in²

Explanation:


1) We know the radius and the lateral area.

2) With the radius you can find the areas of the top and the bottom.

For that, you use the formula: 

area of the top = area of the bottom = π r² 


∴ π (13 in)² = 169π in² (each)


3) Then, the surface area is the sum of the lateral area and the two bases (top and bottom)

surface area = lateral area + bottom area + top area = 325π in² + 2×169π in² = 663π in².

3) You  can also find the height of the cylinder.

Use the formula: lateral area = 2π r h


∴ h = lateral area / [2 π r]

⇒ h = 325 π / [ 2π (13) ] = 12.5 in


4) With  the height you can find the volume.

Use the formula: V = (4/3) π r³ 

∴ V = (4/3) π (13 in)³ = (676/3)π in² ≈ 225.33 π in²

Im struggling to answer this question.
blsea [12.9K]

Answer:

35/100

Step-by-step explanation:

You have 12% of horses (10÷84=0.1190 and 0.1190 = 12%)

You have 54% of sheep (54÷84=0.535 and 0.535=54%)

Subtract the amount of Sheep and Horses for the total amount of animals

84-(10+54)

You have 35% of cows (29÷84=0.345 and 0.345=35%)

35% to a fraction is 35/100 (simplified version 7/20)

I hope this helps (:
