The surface area of the cylinder is given by;
The radius of the cylinder is and the height is
Substitute the values to get;
The correct answer option is 120.
We are given a cylinder with a radius of 5 yard and a height of 7 yard and we are to find the surface area of this cylinder.
We know that the formula of the surface area of a cylinder is given by:
Surface area of cylinder =
Substituting the given values in the formula to get:
Surface Area = = 120
its 60-10+x why, because she bought the dress with $60 and she received $10 dollars back. We don't know the variable.
Answers:k = 13The smallest zero or root is x = -10
note: you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
