10 Circles: circumference an
Using 3.142 as an approximate value for n and giving your answers correct to
3 s. f., find the circumference of a circle of radius:
2.3m 4 53 mm 7 36 cm 10 0.014 km 13 1.4 m
2 4.6 cm 5 8.7m 8 4.8 m 11 7 cm
14 35 mm
3 2.9 cm (6) 250 mm (1.8m 1 2 28 mm 15 5.6 cm

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the answer is d
