Ok so the radius is half the diameter, and the diameter is half the circle. And the area is the space inside a circle. And pie is 3.14.
So if your radius is 10 then you will multiply 10 x 10 to get 100. Then multiply 100 x pie or 3.14 which you will get, 314cm². So your answer is 314cm²
The formula for an area of a circle is radius x radius = ?
Then multiply pie, 3.14 by your new radius x radius, and you got your answer.
Answer:
y+2=1/2(x+1)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-2))/(3-(-1))
m=(0+2)/(3+1)
m=2/4
m=1/2
y-y1=m(x-x1)
y-(-2)=1/2(x-(-1))
y+2=1/2(x+1)
First, you need to find the volume of the cylinder, which is approximately 502.65. Then, divide that by 4 and then multiply by 3 to get approximately 376.99.
Answer = 376.99in cubed
the volume of pyramid B is 4 times bigger than pyramid A
<h3>Volume of a pyramid</h3>
The formula for volume of a pyramid is given as;
Volume = 1/ 3 base × height
Pyramid A
- height = 8 inches
- base = 12 inches
Volume = 1/ 3 × 12 × 8
Volume = 32 inches ³
Pyramid B
- height = 16 inches
- base = 24 inches
Volume = 1/ 3 × 24 × 16
Volume = 128 inches ³
To find the ratio;
= Volume of pyramid B/ volume of pyramid A
= 128/ 32
= 4
Thus, the volume of pyramid B is 4 times bigger than pyramid A
