Answer:
37.699 cm³
Step-by-step explanation:
Sa of cone:
pi×r×l + pi×r²
(3pi × l) + (pi × 3²) = 24pi
3l + 9 = 24
3l = 15
l = 5 (slant height)
Height: h
h² + r² = l²
h² + 3² = 5²
h² = 16
h = 4 cm
Volume = ⅓ × pi × r² × h
= ⅓ × pi × 3² × 4
= 12pi cm³
= 37.69911184 cm³
Answer:
x≤-3 or 2≤x∠7
Step-by-step explanation:
It would be the first answer on the paper
Answer:
78.5
Step-by-step explanation:
The formula for area of a circle is pir^2
So we have 5 for r, so r^2 would be 25.
Using 3.14 for pi, we get the answer is 78.5
100÷4=25
25×4=100
so the answers for the a,b,and c is 25%
It would be 20 no? because there if it is x = x then x = 20 so 20 = x
same thing for all
