Answer:
Answer is 3.5
Step-by-step explanation:
slope is 7/2 which is 3.5:)
True
Area of a circle = πr^2
So if r = 10: area = π*10^2
= 100π
Surface area of a sphere = 4πr^2
If r = 5: surface area = 4π*5^2
= 4π*25
= 100π
Answer:
Buddy you kinda need something to show the surface area of? or do you want the equation to find surface area? for a cube it's A=6a²
Slope=rise/run or
if you have 2 points in (x,y) form then slope=(y₁-y₂)/(x₁-x₂)
the first point is (x₁,y₁) the second point is (x₂,y₂)
we have the points
(-1,3) and (4,-7)
x1=-1
y1=3
x2=4
y2=-7
subsitute
(3-(-7))/(-1-4)=(3+7)/(-1-4)=10/-5=2/-1=-2
slope=-2/1
Answer:
27 in²
Step-by-step explanation:
The area (A) is calculated as
A = πr² ( r is the radius ) , then
A = π × 3² = 3 × 9 = 27 in²
