Area = 2pi*r*h + 2pi*r^2
Area = 2pi*r(h + r)
radius of 7 in and a height of 32 in
Area = 14pi*39 = 546pi in^2
2y = 2x + 10
y = x + 5
m = 1
4x - 12 + 7
4x - 5
4(2) - 5
8 - 5
the answer is 3
The question describes a right triangle with hypotenuse as 9 and one of the angles as 75 degrees. We are looking for the length of the leg adjacent the given angle 75 degrees.
Recall that:
The closest squares greater and smaller than 67 are 64 and 81.
64<67<81
√64<√67<√81
8<√67<9
√67 is in between 8 and 9, so A is the answer.
Hope this helps!
