Answer:
11398.2 cm²
Explanation:
So the formula of the volume of cylinder is already given. We need to put numbers in side of the formula V = Bh to find the volume(V)
so the base(B) can be find by πr² which is π × radius × radius
We know that radius is equal to half of diameter, so the base area is equal to:
22 ÷ 2 = 11 cm
3.14 × 11 × 11 = 379.94 cm
And then we calculate for the volume, the volume formula is above, it is base × height, which is:
379.94 × 30 = 11398.2 cm²
