Please answer both parts. Thank you!

If there are not enough capillaries within a tissue, there may be regions of tissue in which the oxygen concentration vanishes. If such a region, called the anoxic region, persists for prolonged periods of time, the cells would die, and the tissue would be considered necrotic. Using the below data for skeletal muscle tissue, determine: a. The maximum Krogh Cylinder radius, RT, that would avoid any anoxic regions** b. The number of equally spaced capillaries that must exist in the muscle tissue to avoid any anoxic region. R02=1107molcm3s1 Capillary radius =4104cm D=2.0105cm2s1 Oxygen concentration in the blood =4.05108molcm3 Muscle tissue cross-sectional area =20cm2 ** the equation we derived in class for a Krogh Cylinder is applicable to this
