Answer:
37.20 %
Step-by-step explanation:
Circumference = 2 × pi × r
30 = 2 × 3.14 × r
r = 4.7770700637
Area of her face = pi × r²
3.14 × 4.7770700637²
= 71.6560509556 in²
Area of the mask = 9 × 5 = 45 in²
Uncovered area
= 71.6560509556 - 45
= 26.6560509556 units²
% of uncovered area:
26.6560509556/71.6560509556 × 100
37.2%

Answer:
V = 200.96 m^3
Step-by-step explanation:
V=1/3hπr²
h=12, r=4
V = 1/3 (12) (3.14) (4^2)
V = 1/3 (12) (3.14) (16)
V = 200.96 m^3
Answer:
x ≈ 18.9
Step-by-step explanation:
using the cosine ratio in the right triangle
cos19° = 
= 
( multiply both sides by 20 )
20 × cos19° = x , then
x ≈ 18.9 ( to the nearest tenth )
Answer:
right 5 units
Step-by-step explanation:
given f(x) then f(x ± a) is a horizontal translation of f(x)
• if + a then a shift of a units left
• if - a then a shift of 5 units right
f(x) → g(x) = (x - 5)² with a = - 5
then f(x) is shifted 5 units right to obtain g(x)
