Dilation about the origin multiplies every coordinate by the scale factor.
C' = 4(-5, 2) = (-20, 8)
A' = 4(-4, 4) = (-16, 16)
T' = 4(-1, 2) = (-4, 8)
Answer:
the answer to this question is four cups
Step-by-step explanation:
the answer is four cups/scoops because if Zacks cup can hold one cup and it requires two cups to fill each birdfeeder and there are two of them, it should take him four scoops.
Answer:
Step-by-step explanation:
The shape consists of three parts: a half sphere, a round cylinder and a round cone.
The half sphere volume = 1/2 * 4/3 * π * (4)^3
= 32/3 π
The round cyllinder volume = π * (4)^2 * 10
= 160 π
The round cone volume = 1/3 * π * (4)^2 * 3
= 16 π
Adding them together, the volume of shape
= 32/3 π + 160π + 16π
= (32/3 + 160 + 16)*3.14
= 586.13
Similarly the surface area
= (4π4^2)/2 + 2π4*10 + π*4*5
= (32+80+25)*3.14
= 430.18
Answer:
![13.05cm^2](https://tex.z-dn.net/?f=13.05cm%5E2)
Step-by-step explanation:
Area of a triangle is given a half the product of base by the perpendicular height:
![A=0.5bh](https://tex.z-dn.net/?f=A%3D0.5bh)
Given h=9cm, and b=2.9cm, the area is calculated as:
![A=0.5bh\\\\A=0.5\times 2.9cm \times 9cm\\\\A=13.05cm^2\\](https://tex.z-dn.net/?f=A%3D0.5bh%5C%5C%5C%5CA%3D0.5%5Ctimes%202.9cm%20%5Ctimes%209cm%5C%5C%5C%5CA%3D13.05cm%5E2%5C%5C)
Hence, area of the triangle is 13.05 sq cm
