Answer:
17.52
Step-by-step explanation:
literally 11.6 x 1.51 and then round to hundredth place
-7x-3x= -10x
-10x+2=-8x-8
-10x+8x+2=-8
-2x+2= -8
-2x = -8 + 2
-2x= -6
X= -6/-2
X= 3
Answer:
V = 392 m³
Step-by-step explanation:
Volume rectangular prism
V = (1/3)AH
H is the height of the prism
A is the area of the base triangle
A = (1/2)bh
A = (1/2)(7)(24)
A = 84
V = (1/3)(84)(14)
V = 392 m³
Answer:
13. 9.77 inches (rounded to 3 s.f.)
14. 249m² (rounded to 3 s.f.)
Step-by-step explanation:
13. To find the arc length, the formula is the angle of the arc out of 360° multiplied by the circumference of the full circle. Circumference of circle: pi × r × 2
× pi × 7 × 2 = 3pi
= 9.77 inches (rounded to 3 s.f.)
14. To find the sector area, the formula is the angle of the sector out of 360° multiplied by the area of the full circle. Area of circle: pi × r × r
× pi × 10 × 10 = 79pi
= 249m² (rounded to 3 s.f.)
