Answer:
153.938 ft²
Step-by-step explanation:
πr² (area of a circle where r is the radius
π(7)²
π(49)
π(49)≈153.938
KILO=1000.............. MILLI= thousandth
1kg is 1000 grams
1 milligram is one thousandth of a gram, so a 1 gram = 1000mg.
in 36 kg, then there are 36 * 1000 grams.
and in (36*1000) grams there are (36*1000)*1000 mg, 36,000,000 mg.
Answer:
The surface area of the prism is 108 square in.
For every decimal place you move a decimal through a number you can think of it as multiplying or dividing by ten.
take for example 1000.0
if you move the decimal to make this number 100.00 you divided it by ten
if you move the decimal again to make 10.000 you divided ten again
but, if you make the number bigger, say 10000. then you have multiplyed by ten.
Answer:
Scale factor, K = -1/4
Step-by-step explanation:
Dilation of any image changes its size and the shape remains same.
The scale factor is the ratio of dilated image to original image.
Dilation rule: (x, y) → (kx, ky), where k is the scale factor.
It means k = x₂/x₁ or y₂/y₁
K = -5/20 = -1/4 or K = -4/16 = -1/4.
<u>The negative value of scale factor (K) indicates dilations with 180 degree rotation of the dilated image.</u>
Hence the scale factor is K = -1/4.
