Answer:
50.27 square inches (in²)
Step-by-step explanation:
Area = π·r2 = 3.14·42 = 50.27 square inches(*)
d = 8
C = 25.1
A = πr2 = π(d
A = _C²_
4π
π = 3.1415
A = area
C = circumference or perimeter
r = radius, d = diameter
Answer:
12
Step-by-step explanation:
Sides are in the ratio 28:7,
Which is also 4:1
The length of sides of the bigger triangle are 4 times the length of the smaller one.
6x+28 = 4(25)
6x+28 = 100
6x = 72
x = 12
Average rate of change=slope
f(x)=x-5
f(x) could be subsitututed with y so
y=x-5
this is in y=mx+b form where m=slope and b=y-intercept
y=1x-5
slope=1
average rate of change=1/1
if x=-2 then
y=-2-5
y=-7
if x=1 then
y=1-5
y=-4
the graph of y=x-5 is included in the attachment
Answer:
D
Step-by-step explanation:
add all sides together and multiply like a regular square and then divide by 2
