Is anyone willing to me on number 8 9 and 10 i really need you to me with the last 3 problems

C, C and A

Step-by-step explanation:

using the formulae relating to the circle

• Area (A) = πr² ( r is the radius )

• Circumference (C) = 2πr ( r is the radius )

(8)

Area of the interior with r = 4

A = π × 4² = 16π ≈ 50.27 ft² → C

(9)

Area of exterior with r = 7

A = π × 7² = 49π ≈ 154 ft² → C

(1)

Circumference of exterior circle with r = 7

C = 2 × π × 7 = 14π ≈ 44 ft → A

the solution is h=10 because you add 9 to each side of the equation.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
