We know that
surface area of the cone (SA)=pi*r²+pi*r*l
where
r is the radius
l is the slant height
SA=306*pi cm²
diameter=12 cm
r=12/2----> r=6 cm
SA=pi*r²+pi*r*l--------> [SA-pi*r²]=pi*r*l----> l=[SA-pi*r²]/[pi*r]
l=[306*pi-pi*6²]/[pi*6]---> [306*pi-36*pi]/[6*pi]---> 45 cm
the answer is
<span>the length of the slant height is </span>45 cm

Answer:
26
8 2/3
Step-by-step explanation:
4 1/3 ×6
13/3×6
13/1×2=26
2 3/5 × 3 1/3
13/5 × 10/3
13/1 × 2/3
26/3=8 2/3
Answer:
180M (1 round); 900M (5 rounds)
Step-by-step explanation:
Solve for perimeter with is 2L + 2 W.
1. 2(50) + 2 (40) =
2. 100 + 80 = 180
He walked 180M for 1 complete round. To determine 5 complete rounds, multiply by 5.
180X5= 900 M
