Answer: 423.11 m^2
Step by step explanation:
Area of a circle formula pi*r^2
First solve the area of the big circle
3.14*21^2=1384.74 m^2
Now find the are of the smaller circle
r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2
Now we can minus the small area off the big area to get the shaded area.
1384.74-961.63=423.11 m^2
So the area of the shaded region is 423.11 m^2
Answer:
x=42.3m
Step-by-step explanation:
x/47=82.8/92
92x=3891.6= 42.3m is the distance
Answer:
$1522
Step-by-step explanation:
M = 7 + 3*J
M = 7 + 3*505
M = 7 + 1515
M = 1522
Answer:
n=-1
Step-by-step explanation:
First you add 5 to both sides an you would get -15n=15
Next divide by -15 on both sides and get n=-1
