Area = 64π x 4
A = πr2<span>.
r = √(A/π)
radius = 16</span>
Answer:
FIRST ANGLE = 21 degree
SECOND ANGLE = 119 degree
Step-by-step explanation:
140 = 6x - 7 + x
140 = 7x - 7
combine like terms
140 + 7 = 7x
147 = 7x
x = 21
second angle = 6(21) - 7 = 119
Answer:
Answer is below
Step-by-step explanation:
Subtract 2x from both sides.
Subtract 15 from both sides.
Divide both sides by -1.
So therefore your answer is 15
Answer:
22.
Step 1: Find area of inner square = 4 ft × 12 ft = 48ft2
Step 2: Find area of outer shape =
25 ft +11 ft = 36 cm2
Step 3: Area of shaded region = area of outer shape – area of inner square
= 36 ft2 – 48 ft2
= 12 ft2
