Answer:
Draw a picture and you'll see a right triangle with sides = 7 and 24 and hypotenuse = r (the cricle's radius). By the Pythagorean Theorem:
r2 = 72 + 242
Area = pi·r2
Step-by-step explanation:
Answer:
V=349525.333*pi
Step-by-step explanation:
Volume of a sphere: V=(4/3)*pi*r^3 where r=radius.
r=64
V=(4/3)*pi*(64)^3=(4/3)(262144)pi=349525.333*pi
Answer:4
Step-by-step explanation:
Answer:
(a) 3
Step-by-step explanation:
Calculate the slope m of the line given using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0,3) and (x₂, y₂ ) = (3, 2)
m =
= - 
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 3 → (a)
Let the four consecutive numbers be x, x+1, x+2, and x+3.
The sum of the four numbers is 54, therefore
x + (x+1) + (x+2) + (x+3) = 54
4x + 6 = 54
4x = 54 - 6 = 48
x = 12
Answer:
The four numbers are 12, 13, 14, and 15
