Answer:
25 ft
Step-by-step explanation:
The area of this landing pad is 1,962.5 ft², which equals πr².
We solve this equation for r²:
1962.5 ft²
r² = ----------------- = 625 ft²
3.14
Taking the square root of both sides, we get:
r = √(625 ft²) = 25 ft
The radius is 25 ft.
Answer:
So total number which is not divisible by 11 = 89999-8181 = 81819
Step-by-step explanation:
We have to find the total numbers which are not divisible by 11 from 10000 to 99999
Total number from 10000 to 99999 = 99999-10000+1=90000
Just after 10000 the number which is divisible by 11 is 10010
And just below 99999 the number which is divisible by 11 is 99990
Using AP formula
, here a is first term, d is common difference and n is number of terms
So 
n-1 = 8180
n= 8181
So total number which is not divisible by 11 = 90000-8181 = 81819
Answer:
EF = 10
Step-by-step explanation:
QUICK
9/15 = 6/x
x=10
First isolate y for each equation so that y = x^2 + 3 and y = 2x^2 + 2 now set those equal to eachother and solve for x,
x^2 + 3 = 2x^2 + 2
= √x^2 = <span>√1
x is +- 1
then plug in x for one of the original equations y = 1^2 + 3 = 4
x = +-1
y = 4</span>
