Answer:
B .-12 and -12
Step-by-step explanation:
it is because when we multiply two -digit the answer is in +
so like in the same -12 * -12=144
And when we add the digit we get -24
Hence, it is proved
Answer:
2.25π in²
Step-by-step explanation:
The area can be found from the circumference using the formula ...
A = C²/(4π)
Putting in the given dimension, you have ...
A = (3π)²/(4π) = (9/4)π = 2.25 π . . . . in²
Answer:
Step-by-step explanation:
volume = area of base * height = area of base * 9 = 72
-> area of base = 72/9 = 8
let a,b,c be the length of sides of isosceles right triangle base
we have a = b and a*b/2 = 8 ft2
-> a*a/2 = 8ft2
-> a*a = 16
-> a=4ft=b
have c^2 = a^2 + b^2 = 16 +16 = 32
-> c = 
= 5.656 ft
Since i dont know that is DF, i calculate both a,b and c
