![**Problem 11**
Let \( W_1 \) be the solid half-cone bounded by \( z = \sqrt{x^2 + y^2} \), \( z = 2 \) and the yz-plane with \( x \geq 0 \), and let \( W_2 \) be the solid half-cone bounded by \( z = \sqrt{x^2 + y^2} \), \( z = 3 \) and the xz-plane with \( y \geq 0 \).
For each of the following, decide (without calculating its value) whether the integral is positive, negative, or zero:
(a) \[ \int_{W_2} \sqrt{x^2 + y^2} \ dV \] is [?/positive/negative/zero]
(b) \[ \int_{W_2} yzdV \] is [?/positive/negative/zero]
(c) \[ \int_{W_1} xy^2 \ dV \] is [?/positive/negative/zero]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbbff2935-77bb-4550-bfd1-d595e6271f30%2Ff9e202af-71ec-426c-8ffc-092765623945%2F8m22ei_processed.png&w=3840&q=75)
