Answer:
Step-by-step explanation:
Answer:
Area: 5π/2 in²
Perimeter: (3π+2) in
step-by-step explanation:
Area =
larger semicircle + small semicircle
= ½(pi × r1²) + ½(pi × r2²)
r1 = 2 in
r2 = 2/2 = 1 in
Area:
½(pi × 2²) + ½(pi × 1²)
= 2pi + ½pi
= 5pi/2 in²
Perimeter:
½(2pi × r1) + ½(2pi × r2) + r1
½(2pi × 2) + ½(2pi × 1) + 2
2pi + pi + 2
3pi + 2
Answer:
10.67
Step-by-step explanation:
The 10 stays as it is. The 2/3 is approximated by 0.67 (to the nearest hundredth). Thus, we have 10.67 to the nearest hundredth.
