Answer:
volume of cylinder= pie × radius square× height
= 22/7×4×20
=1760/7
=251.42cm
Answer:
using 3 for pi it's V = 960cm^3
Step-by-step explanation:
R is the radius, which as stated, is half the diameter.
r = 8cm / 2 = 4cm
H is the height, which is shown to be 20cm
h = 20cm
V = pi*r^2*h
V = pi*(4cm)^2*20cm
substituting 3 for pi as requested.
V = 3*(4cm)^2*20cm - 3 * (16cm^2) * 20cm = 48cm^2 * 20cm = 960cm^3

Marley walked around 2 rectangular parks. One measures 54 feet by 38 feet and the other measures 32 feet by 22 feet. How far did she walk?
Answers
Answer:
Step-by-step explanation:
Perimeter of Park 1 = 2*(54+38)
= 2 * 92
=184 feet
Perimeter of park 2 = 2*(32+ 22)
= 2 * 54
= 108 feet
Total distance = Perimeter of park 1 + perimeter of park 2
= 184 + 108
= 292
A 1,300 kg car moving at 20 m/s and a 900 kg car moving at 15 m/a in precisely opposite directions crash head on. If we consider this event to be a perfectly inelastic collision, what is the speed of the cars after the impact?
Answers
Answer:
17.96m/s
Step-by-step explanation:
Based on law of conservation of momentum;
m1u1 +m2u2 =(m1+m2)v
v is the velocities of the car after impact
Substitute the given values
1300(20)+900(15) = (1300+900)v
26000 + 13500 = 2200v
39500 = 2200v
v = 39500/2200
v = 17.96m/s
Hence the speed of the cars after impact is 17.96m/s

The storage box for a flag is in the shape of a triangular prism. What is the surface area of the box?
Answers
*see attachment for the diagram of the triangular prism box
Answer:
528.8 in.²
Step-by-step explanation:
Surface area of triangular prism = 2(BA) + P*H
Area of triangular base (BA) = ½*b*h
b = 24.5 in.
h = 12 in.
BA = ½*24.5*12 = 147 in.²
Perimeter of triangular base = 24.5 + 17.1 + 17.1 = 58.7 in.
Height of prism = 4 in.
Plug in the values into the surface area formula:
Surface area of prism = 2(147) + 58.7*4
= 294 + 234.8
= 528.8 in.²
The ratio of cakes to cookies in the bakery was 3:5. If there were 90 cakes, how many cookies were in the bakery?
plz help
Answers
Answer:
150 cookies
Step-by-step explanation:
Using the ratio as an equation we can divide 90 by 3 to find the common multiple used to simplify this equation into a more usable ratio.
3 : 5 90 : 5x (x is the common multiple)
90 / 3 = 30, so x is 30
Then we multiply both sides of the original ratio by the common multiple to get our answer.
3 : 5 is equal to 90 : 150

[tex] - 11 \frac{1}{2} [/tex]
Step-by-step explanation:
8x + 5y = 7
4x - 5y = 11
If you all it all up we have
8x + 4x +5y - 5y = 18
12x=18
x=18/12=1.5=3/2 = 1 whole number 1 over 2(1 1/2)
subtituting the value of x into equation 1(8x + 5y = 7)
8(1.5) + 5y = 7
5y=7-12
5y = -5
y=-5/5
y= -1

Answer:
Adjacent angles. x = 55
Step-by-step explanation:
Adjacent angles are angles that are right next to each other, sharing one side.
Since that is a right angle (90º):
X + 35 = 90
X + (35-35) = 90 - 35
X = 55

.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?
Answers
9514 1404 393
Answer:
90°
Step-by-step explanation:
The largest angle is 6 of the 6+1+5 = 12 ratio units, so is 6/12 = 1/2 of the total number of degrees in a triangle.
The largest angle is 1/2(180°) = 90°.
