Answer:
628.32 in.²
Step-by-step explanation:
Height: 15 in.
Diameter: 10 in.
Radius: 5 in.
A = 2πrh + 2πr²
2 · π · 5 · 15 + 2 · π · 5²
≈ 628.32
Answer:
False.
Step-by-step explanation:
A tangent is a line that only touches exactly one point of the circle. (The outer edge) :)
V = l x w x h. Area of the base if also lengh x width, so V = ( area of the base) x h 18 = 4.5 x h.So height : h = 18 / 4.5
Step-by-step explanation:
step 1. break into 2 shapes: a rectangle of sides 3 and 4. a triangle of sides (x - 3), 4, and y.
step 2. y = 4sqrt(2) (definition of a 45° triangle)
step 3. note: sqrt is the square root.
step 4. x - 3 = 4 (definition of a 45° triangle)
step 5. x = 7 (add 3 to both sides).
X<span>(6 + </span>x)(x<span> + -4) = 24x ... + 2x</span>2<span> + </span>x3<span> = 0 </span>Factor out<span> the Greatest Common Factor (GCF), '</span>x<span>'. </span>x<span>(-48 + 2x + </span>x2<span>) = 0 ...
