Answer:

<h2>Area Semicircle = 1/2 πr² </h2>

where

r radius of semicircle

→ ½ * 22/7 * r² = 35

→ 11/7 * r² = 35

→ r² = 35*7/11

→ r² = 245/11

→ r² = 22.77

→ r = √22.77

→ r = 4.77

Therefore,

Diameter = 2*4.77

= 9.54 cm

antiseptic1488 [7]

Answer:

The scale factor is 4.5

Step-by-step explanation:

Scale factor from ∆RST to ∆XYZ = side length of ∆XYZ / corresponding side length of ∆RST

Thus:

XY corresponds to RS

XY = 45

RS = 10

Therefore:

Scale factor = 45/10 = 4.5

Scale factor from ∆RST to ∆XYZ = 4.5
