Answer:A for the first one and C for the second one
Step-by-step explanation:
Answer:
T F T T.
Step-by-step explanation:
Let p and q be two statement
When the value of p is true and the value of q is true then the value of
is true.
When the value of p is true and the value of q is false then the value of
is true.
When the value p is false and the value of q is true then the value of
is false.
When the value of p is false and the value of q is false then the value of
is true.
Hence, the value of
is false when q is true and p is false.
VOLUME = 4/3 pie radius ³
Answer:
4.78 cm
Step-by-step explanation:
The formula for the volume of a cone of radius r and height h is
V = (1/3)πr²h. Here, V = 31.254 cm³ and r = 2.5 cm.
We begin by solving V = (1/3)πr²h for the unknown height, h:
31.254 cm³ 3(31.254 cm³) 93.762 cm³
h = ------------------------ = -------------------------- = -------------------- ≈ 4.78 cm
(1/3)πr² π(2.5 cm)² 19.635 cm²
