£42

Step-by-step explanation:

Let the money they share be x

Hence, 5:3 in the ratio Carly and James

Meaning Carly gets 5/ (5+3) × x = 5/8 x

But 5/8 x= £70

Meaning x = £70 × 8/5 = £112

But James gets 3/8 × x = 3/8 × £112

= £42

$\large\boxed{L.A.=168\pi\ in^2}\\\boxed{S.A.=232\pi\ in^2}$

Step-by-step explanation:

The formula of a lateral area of a cone:

$L.A.=\pi rl$

r - radius

l - slant height

The formula of a surface area of a cone:

$S.A.=\pi r^2+\pi rl$

We have r= 8in and l = 21in. Substitute:

$L.A.=\pi(8)(21)=168\pi\ in^2$

$S.A.=\pi(8^2)+168\pi=232\pi\ in^2$
