Answer:
2310m^3
Step-by-step explanation:
base area which is the circle = πr^2
But diameter, d = 14, r = 14/2 = 7
area = π × (7)^2 = 22/7 × 49 = 22 × 7 = 154
Volume = base area × height
= 154 × 15 = 2310

Can you clarify?
Step-by-step explanation:
Answer:
ED ≈ 2.6 units
Step-by-step explanation:
Using the Sine rule in Δ DEF
= 
=
( cross- multiply )
ED sin115° = 6.95 sin20° ( divide both sides by sin115° )
ED =
≈ 2.6 ( to the nearest tenth )
