Plug in the given values and you'll see its option 2.
x=0 , f(x) = 0^2 + 1 = 1
x = 1 , f(x) = 1^2 + 1 = 2
x = 2, f(x) = 2^2 + 1 = 5
Hi there!
Using the equation for the area of a circle, we can simply substitute pi with its numerical value of 3.14 and r with the radius given.
1.) Area = (3.14)(6cm)² = 113.0 cm²
2.) Area = (3.14)(28in)² = 2461.8 in²
3.) To find radius, first we must divide the diameter in half. So, 11/2 = 5.5 ft
Area = (3.14)(5.5ft)² = 95 ft²
4.) Similar to 3, to find radius, first we must divide the diameter in half. So, 10.5/2 = 5.25 in
Area = (3.14)(5.25in)² = 86.5 in²
5.) Area = (3.14)(6.3mm)² = 124.6 mm²
6.) Area = (3.14)(3
yd)² = 33.2 yd²
When you divide 4.24 and 40 you will get 0.106
Well first you would just have to look at the equation for the volume of a pyramid. This is:
V = (length * width * height) / 3
and so we can just say all pyramids have a volume of V.
So now we want the base to be 3 times bigger which means we would have to multiple the length and width by 3 and the new volume equation would be
V = (3*length * 3 * width * height) / 3
we can factor the two 3's from the parenthesis and get
V = 9(l * w * h) /3
if we are looking at a ratio of how much the volume increases we can say
aV = b(l * w * h) /3
since:
V = (l * w * h) / 3
then:
aV = bV, divide both sides by V and:
a = b
using this we can see that the volume increases by a factor of 9 for 3 times bigger
now for 6 times
V = (6 * l * 6 * w * h) / 3, pull 6 * 6 out
V = 36(l * w * h) /3
and this one increases by factor of 36
if we see a pattern it always increases by the square of the factor of the growoth of the base
so for 9 times bigger it would be 9^2 = 81
and for 27 times bigger it would be 27^2 = 729
